I am sorry you are struggling.
This is a long thread, so I'm just going to respond to your original post, ok?
1. I feel once again devistated because the GF went behind my back and invited him when she knows it's part of our boundaries. He went along with it, by just saying yes and not finding out where they were going.
You do not talk to her direct. Your hinge tells you what she said. He could stop telling you so you don't have to know her behavior and get upset twice over.
In her behavior? If she knows an agreement between (you and DH) and continues to invite him to break it? She is not being respectful of HIM or HIS agreements with his spouse. He could call her on that.
YOU could call him on telling you crazy you don't need to know which only adds to your burden. Esp. when he does not ALSO share that he called her on disrespecting agreements he shares with you.
-1 for her for not respecting
-1 for him for TMI-ing you and not telling her to respect his agreements with his spouse
-1 for him for not telling her to respect his agreements with his spouse
2. She says that I am being controling but from reading 100s of posts here, it was my understanding that the primary partner is perfectly in their rights to nogiate what their partner can and can't do. For example, many people don't want their partner to KISS someone before meeting them...are my standards too high? Am I being controling?
Your spouse was not
coerced to agree to anything with you, right? He co-created an expected standard of behavior with you that both agreed to uphold? If so, HE has agreed to control HIS own behavior to fall within those boundaries.
If his GF has a problem with HIM controlling HIS behavior, she can take it up with HIM. Leave you out of it.
It is not you being controlling. It is her not wanting to help him keep agreements with his spouse. Just like she could expect you to help him keep agreements with her.
One does not play "tug of war" with the hinge person and make life hell for the hinge. It is not loving or kind behavior.
If your spouse is telling her "my spouse won't let me" garbage rather than "I have agreements to keep with my wife" -- he could think about how he phrases things and OWN his own behavior. You could call him out on that.
3. They invited me (after it all came out) to attend the sex party. I am thinking of doing it so i know what it's like in reality versus my imagination. I am curious and very slightly turned on, but I have had bad experiences with friends doing meth and having orgies. I am also pretty sexually conservative. Frankly, I'm scared and grossed out to go...should I go?
If something scares you and grosses you out, you could respect your own limit of tolerance and choose not to attend.
If you are curious and aroused, and this is greater than the gross out/fear factor, you could go and choose to change your limit of tolerance.
Only you can know the answer to what you are willing/able to do in this case.
4. GF says she feels secondary. But she wants him to herslef. Doesn't want to be friends with me or our kids...I guess she wants him once a week and as if he's single ie no boundaries or calls from me...
If she wants to be with a single man, she could date a single man.
If you currently call him on their dates and it is not to agreed to boundaries? You could not do that. You would not like her calling on (you+him) dates to shoot the breeze.
If you and spouse agreed to practice a primary-secondary open relationship model, and she agreed to participate as a secondary, she could not be surprised she is a secondary who sees him once a week and he has agreements to keep with other partner.
If she wants to renegotiate boundaries, she could ask (you), (DH) and (You + DH) if you are willing to do so and change the boundaries of the polyship, including the structure of this open model relationship to change from (primary-secondary) to some other model. Then (you) and (DH) and (you+ Dh) are free to consider if you are indeed willing to do that or not.
Or she could stop participating in the polyship as it stands if it does not meet her needs.
Any of you could, even you.
Any advice? The other issue is there is no communication between her and I .. only "she said" from husband. She doesn't WANT to communicate with me. I told husband why didn't they just come to me and talk. Even if I said no, at least we were communicating. But, she prefers to sneak...
What was the polyship's agreed to methods for communication? If they no longer serve at this time, you could all talk to see about changing that.
At this time, if the agreement is "separate but equal" communication and you both find yourselves struggling with "sloppy hinge" because he leaks all over the place, you each could ask your hinge to STOP telling you stuff that belongs on the other side of the "V" because it creates problems.
In this case? With the party?
You seem most mad that nobody came to you first above.
Since the GF prefers to not talk to you, it would fall on DH then to renegotiate that if he wanted to attend without breaking agreements with you. He could have said
"Hey, my GF invited me to a sex party. I told her I cannot because I have agreements to meet with you. But in future I think I would like to attend one. Could we talk about that boundary and renegotiate? Would attending one help you consider changing that limit"
Instead you seem mad at the GF because she appears to be the trigger, and while she has some stuff there she could own, the closer problems seem to to be with DH in his role as hinge. He's not one not holding up his end of the stick on your shared agreements -- not her.
