You still don't have any evidence of an A. I don't know why you can't accept the fact that maybe your W was tired of putting up with your issues for so long and just wanted out. Your bipolar issues could be making you paranoid and you can't seem to let certain things go.
"I could definitely see myself getting to know her a lot better down the road. "
It's very obvious that this was your original intention. So why don't you go ahead and file already? I mean, you haven't fully worked on yourself so want to medicate your hurt feelings with another woman. Problem is that because you haven't worked on yourself, the same issues are going to come up.
Sure you'll be "in love" with this new woman. But how long until your insecurities start coming up again? You'll start see the guys she talks to as threats or that she may be having an A, etc. And the cycle goes around again.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
