While I wouldnt be happy about it, I could probably bounce back from my SO having an EA. I made some serious mistakes with my SO including neglecting her emotionally and that drove her away. It's a PA that I cant/wont accept.
I want to cut it off and turn things around between her and I before it becomes physical.
And I wanted to state that she and I were never married, we were engaged, living together, and have a duaghter, and were together overall for over 7.5 years. But our relationship was closer to a M than it was simple bf/gf. However...now that she's moved out, our situation is almost like a D.
And I did state a boundry to her that if she chose to move on with this OM, I would not continue to be friends with her and we would have no contact other than exchanges of our daughter and medical emergencies with her. Many here have said that's a weak boundary but since we arent M, it's the only boundary I feel I can set other than saying until she stops being interested in/seeing OM we'll have no contact.
As it stands now she's being friendly with me and has engaged me in family activities...no real one on one time. I'm thinking if I were to cut her off now with that alternative boundary, she would just see it as a chance to pursue the OM in peace.
