Estranged fiance was misdiagnosed BiP

[How to communicate after a contentious divorce...]

Hello I ve recently broken up with my fiance.we ve been together for 4 and a half years.we ve been split for just over 2 months.she s already been with a guy right after we split.she was misdiagnosed bipolar when we first met.after we split I thought something was up.after research I thought she fit BPD to a tee.she was never this bad but a lot of stress in our lives helped bring it out.she was drinking a lot and so was I. I found out she was doing coke after she left.right now her emotions are all over the place.last week we were buddies and kept saying we loved each other now this week she s acting like we re just friends.I think she s fishing for yet another boyfriend since the last one has already fell through.she was all in tested last week until she found tinder.we split 2 years ago and she hooked up right away and everything is exactly the same now.we have a house together and a life and she just up and left.everybody who is close has seen the mass change in her.I went with her last week and she s finally been diagnosed with BPD.I want to try again but she is getting farther away.I scared that if she isn't with me she will not take the therapy seriously and will never have a normal life.what should I do in my situation.I think she s trying to find or by now already has found another replacement.one day she loves me the next she s cold as hell.I don't want her to throw everything away because she has a lot to loose.I think I m her back up right now.she s been lying a lot and I know what she s doing.part of me says leave her be and another wants us to work it out.

Hi Buncha,

I'm sorry to hear that. You have shared your life together for the last 5 years and you have responsibilities. I can see how it's not that easy to just walk away. She left 2 months ago? Is she staying with family and friends? Do you have kids together?
