Thinking outside the box
What are her choices that would empower her and put her in a position of maybe salvaging her relationship?
Did you ever notice a couple who was having an affair in your office? Their NRE or new relationship energy is very hard to hide from others (oxytocin high/adrenalin high, when they are in each other's presence). Your BF caught you in that high when you were with your new beau. Your BF might translate that to, "Oh no you don't! I saw you oozing with giddy-girl syndrome around him. Oh hell no. He doesn't get to take you away from me."
In any of the books you will see that the r'ships that survive will have a hierarchy. The couple at the top making decisions for the rest of the people in the bottom corners. The mistake here is the new beau made the decision with you for your r'ship. Bad news, but it can be cleaned up. I hope BF doesn't know that.
Why do I think I was mostly successful? Hubs and I were making decisions for the rest of the r'ship. Mostly I was, empowered with more info, with him in mind. Reassurance goes a long way to help the r'ship, but is short lived, so use the broken record technique, with a loving tone.
Since your BF is feeling really threatened by your beau, seeing the twinkle and new life he brought to the damsel in distress, I will make this suggestion, if you can follow through. He is correct to think, "Ruh roh, he is trying to take her away." Most of society would think this.
One suggestion that may be out of the box, but not unheard of: if your goal is really to get sex and intimacy with a neat man, you can get that soon. If you want to get sex and intimacy with your new beau with more acceptance, add more men to the mix. Be a hotwife. I have a mentor who a couple enlisted to basically have sex with the wife. This man is unable to have sex,but does not want to take away his wife's pleasure of sex. He enlisted my mentor because he is safe. He is in a sexless marriage where he dearly loves his wife. This man doesn't allow his wife to see a man more than once a month.
I mean, she sees a different guy each week, skipping some weeks. Remember I talked about boundaries and rules? So she rotates a few really fine lovers. It is easier for us women to collect men. Although my mentor has sex and intimacy with three lovely sweet women. Has been doing so for many years. Openly.
I wish I had gone this direction. I think my hubs would have been more comfy with this, rather than just one guy for several yrs. I have had 2 separate men, because I wanted sex 2-4 times a month. Now I see MM almost every week.
How did I reassure hubs? I got my opposites in ways, and told him that is what I would search for. I would be searching for my opposite to be less threatening to my hubs. All the little things do help to reassure him.
MM is the opposite, politically, and in other ways, a business man who travels to me. He is a certain type hubs knows I have never gone out with, He was a literal model I plucked off the streets. (I won't let H see his pics. He does not know MM was a model.)
I looked for a sweet, amenable, touchy-feely man who was open to exploring new sensations while mattress dancing. A mix of gentle with some rough manliness.
I had originally started to hang out in an erotica/fetish/lifestyle forum. I told myself that was going to be my sex-- watching others in action and dreaming. I was no longer ignoring romantic movie scenes.
I was starving. I told H to have one of his colleagues that he trusted to shag me. NOPE. His morning smile melted into a frown of silence. Then one morning, without planning, I said "Lovey, I am going to step out of the marriage for sex.
I was shaking in my boots. I felt hot.
He said, "Do, and that is where your r'ship will lie."
A therapist friend asked, "What did you do? That is very emasculating."
I went to therapy to clean it up, best I could. I told hubs my goal was sex. Only sex. I had no clue how much intimacy I needed. I don't reveal my intimacy needs to him. He knows how I am. I feel it is a burden to his psyche and my own.
I asked MM if he could handle me being in love and attached to him, but we each knew our place in the r'ship.
Hubs would always be number one. His wife and family and work would always be his number one. He agreed it would be possible to be in love, but be someone else's love, as well. It was neat to have different men who cared.
Hubs said, "Wait! That is embarrassing. What do I tell ppl who see you out with others?"
I said: "You tell them that you allow me to go out with others for male fellowship, as always. That is what you tell them."
Only then did he start to accept this more. What will I tell him when he asks about MM again? I will tell him, "Silly, you know I will have several men in my life to get myself some sex, if I can." I can reiterate my boundaries that I have in place with MM.
If your BF is like my hubs, I would start a search to get the focus of new beau and put it on sex. The search was exhilarating. I got 120-ish responses in one day. Not all quality. Put a phrase in that lets them know they have read your profile. Throw away the others.
I told hubs I would not be revealing details because it felt weird to me and I did not want to hurt him. If he was gung ho about my finding sex outside, I would have revealed more gladly. He mostly lived inside his head in silence, clamming up. Will he be more anxious about this one dude or more anxious about seeking several dudes? You tell us.
TellBF that this Valentine's Day is much more important to you than others, and you need to both plan something extraordinary for each other. A weekend trip with intimacy, like his and her massages, and no sex, so he feels safe.
After Christmas and Valentine's Day, the dating sites are littered with people for a reason. They are feeling unwanted and lonely. Ashley Madison gets it biggest boom of the year.
Tell BF to spend no less than 5 hrs in prep for Valentine's Day. You do the same. Don't fall into the trap of "If he loved me he would." He is incapable of being nurturing right now. He is lost. My H dove into books and ran so much he hurt his knee and needed surgery. Our world was caving in on us temporarily.
Just ideas that may not fit. I think poly folks and hotwives can teach us a lot. Look them up.
Remember that people don't reveal all their private sexual rendezvous. Why should we have to? It hurts our mate. I told hubs I would reveal what I was comfortable with, but mostly I would sooner or later go into hiding as much as I could so I would not hurt him or myself. I won't reveal all my sexual details and intimacy. Then I went into an underground cheater/philanderer's forum, even though I am open.
DADT spared my hubs a lot of anxiety. Wow, who knew? He wanted to ignore what I was doing as much as he could. Finally, I figured out not to rub it in his face. That is what he felt I was doing. I was just trying to be honest so he would not worry about me. I even told him I was feeling so uncomfortable that I would lie to not hurt his feelings, so don't ask me about certain details, unless he wanted a generic lie. I would not make a good philanderer and I don't feel comfy revealing what I do.
I tried, "Hey love, just calling to let ya know I am with my friend at the hotel," but it turned into, "When I say I am going for ice cream, I am uncomfortable and will not be telling you any other details," which led to, "I am going to the grocery store in the next couple of days. Do you want anything?"
He felt so powerless in this situation that he started telling me, "No, you can't watch that TV program. No, we are not going to buy that!"
"Lovey, will you do me a favor?"
"No."
He moved out of the master bedroom. I cried, and then went and tucked him in at night and just laid with him.
MM told me, "Oh no, he is feeling helpless. Hope he pulls through."
He gradually came out of his terrible twos and back to being my loving hubs. He did this off and on for about a yr.
Some will say, that is too much work. Yes, but I had gone over a decade of trying. So another yr of hard work was a drop in the bucket. I have been with MM for several yrs when I had originally agreed to go 6 months and check back in to see if we would return to sex.
For me, instead of getting in trouble for an affair, I got in trouble upfront by telling him my intentions. I was getting sex one way or another. Then it gradually got better.
If someone knows of other examples of sexless marriages that worked/didn't, let me know. Not many models around and sometimes I am lost. I think it is the most lonely feeling in the world, showing love through intimacy and sex without reciprocation.
If this does not help you, maybe it will help someone else.
An important note is that it took several months to find a neat man after my mentor said: "Dump your pen pals and get serious about finding a guy."
This book was one I wanted this year because it rated higher than others.

More Than Two: A practical guide to ethical polyamory
Surely we won't all agree on a path. There is no right or wrong.
What if you set up a therapy appointment and go in alone? Bring him in later. Make sure the therapist is poly-friendly. They have a list here. If not, consider doing therapy over the phone, if covered. Remember that a therapist will ask him what he wants, and respect his wishes, after pointing out the consequences for scenarios.
