My W's older sister is also Bi-Polar but I dont believe she is BPD. She went through the same thing I am going through 2-1/2 years ago with her H. I still talk to him all the time and even though they are divorced and he is still with the OW he regrets everything, misses my SIL horribly and has fallen in love with her again. He has told me that everything my W tells me is word for word what he told my SIL when they went through it and that it was all wrong and he was caught up in the excitement of the OW.
Last night (and today) I had my daughter and she is sick so I had to talk to my W on the phone this morning. I made sure that there was no negative talk, no talk about our relationship, and that everything we talked about was for my daughter only. Several times I tried to cut off the conversation cuz she was getting ready for work and needed to get going but she kept stalling and continuing the conversation. That was kind of encouraging and brings me just a bit of hope.
The other night when we talked on the phone she said we should work on trusting each other then work on being friends again. Should I take this route or continue to give her her space and keep all communication about our daughter only?
