Looking for some suggestions...
My wife has been pushing for us to talk about her relationship with this new man (I will call him "B") over the last couple of days. After feeling like my repeated attempts to set a boundary were being rebuffed, I got frustrated and we had a very heated argument about the degree of intimacy that we could agree on in her relationship with B. I can feel this sick feeling coming up every time I think about my wife and B being intimate. I have never seen the two of them kiss, but I'm aware that this is going on outside of my presence, and I can accept that. But, for some reason, I cannot get past this block when it comes to sexual intimacy.
I honestly did not expect this to happen when we approached this point. I have two clear incentives for promoting their relationship. I want my wife to be happy, and it's clear to me that she is falling for B and wants to follow her feelings and desires. I want my relationship with G to continue to grow and I want to, eventually, be free to express my love for her without excessive limitations. Logically, it all makes sense, and I understand why I want to let this happen. But emotionally, I am a wreck. I barely slept last night and am completely drained this morning.
Combined with the recent developments in my relationship with G, the last few days have been an emotional roller coaster for me.
I asked my wife for time to try and sort all of these feelings out. To figure out why this bothers me to the extent that it does. While she was frustrated at my hesitance in opening the boundaries further (I can completely understand), she agreed to give me the time I need to figure this all out. I was careful to not agree to a certain time frame and made it clear that I have no idea how long, or even if, I will be able to move past this. While we have been identifying as polyamorous for months now, this is the first time either of us has had to consider and process the reality of our partner having sex with another lover of the opposite sex.
In addition, I have a much better understanding of M (my gf's husband) and his own confusion, jealousy, and hesitancy in opening his relationship to an equivalent level. I didn't have a frame of reference to his situation before now, and I feel for him deeply. I sincerely hope we are both able to overcome these fears and move forward with our relationships.
So where do I go from here? Any suggestions for how I should approach tackling this emotional muck that is coming to the surface for me? How I can identify what is triggering this and try to see it for what it most likely is, an irrational fear?
