<human>: Can you condense the text into three sentences or less?

So we were together for 8 years, polyamorous. This ex transitioned from bi female to gender neutral queer within that span of time. Met someone in the queer community, and our relationship came to an abrupt end. Then they closed off all contact with me and I left them alone. we have barely said a word or seen each other for three years now. 

The thing is, our mutual friends still feel the need to chose between us in social gatherings and this person always "wins". People I went to college with. People my ex wouldn't know if it wasn't for me. Now evidence of past social gatherings keep springing up in social media that are constant reminders of how I am deliberately being excluded from events and I know they are trying to hide it from me. they're just really bad at it. And, fuck, it hurts. 

After the break up, i went out of my way to let people know I wouldn't put them in a position to choose between us but it's inevitable that it will happen in some form i just had no idea it would be on such a grand scale. I just figured people would have let it go after three years. My only theory is that my ex is the one who put the clause that they don't want me around, sharing social space so our mutual friends have to choose. And it seems they have chosen. 

I just miss my friends and i think my ex is the only person who can diffuse this situation. I was considering reaching out and, maybe, hopefully working something out to where we can at least share social space again. 

Thoughts? Should I take a shot at it or just let it go and continue to make new friends. Suggestions of approach?
<bot>: I'm considering contacting an ex after 3 years to diffuse social tension so our mutual friends won't have to feel like they have to choose between us/Should I take a shot at it or just let it go and move on?
