Ex GF - Possibly bipolar? I ask because I still care

Hey all,

So as I write this I want you to know why I find myself posting a couple times on this forum. My ex gf broke up with me about 1.5 months ago and I still find myself missing her everyday, although I feel like a lot of the time that I am over her. Her and I have to work together this September for 8 months and it is going to be an interesting experience for sure. Back story: She left me quite suddenly after changing our relationship status and texting me a few paragraphs about what I did wrong and that she can't be with me anymore. She said that my irritableness had scared her and that she had gotten anxious to speak with me, worried that I may become irritable about something. I know that it's perfectly fine for her to feel that feeling but I want to delve a bit further. She broke up via text and didn't give any signs before-hand that eluded to a breakup being immanent. She said she wanted to make it work, but felt like she couldn't handle it and she was feeling bad when she thought about being together again.

Since talking with a lot of people and my psychologist, I am hearing a lot about myself and how to help myself become better, but also a lot about what they feel she may be going through. I know that she is depressed and has anxiety, but some people have shown me info on BPD and lots of the content (90%) seems to apply to my ex. I wanted to know more about the possibility of BPD affecting relationships, as well as how it could've affected her feelings towards me, more so than without it.

Her friend did un-add me on Facebook before the breakup which I realized now is probably not a coincidence, but I didn't think much of it at the time. My ex has also blocked me on Insta and Snapchat, and I blocked her on Facebook. Could this be a way of her coping with not being/wanting to be in contact with me?

Is there anyone who knows whether BPD could've had a role to play, and if so is there any time where you think she will reach back out to at least talk/discuss things with me?

Also, what do you feel about this kind of thing happening; does Bipolar Disorder have a negative impact on most relationships?

I want to know more so that I can move forward knowing that I did what I could and that even with my helping hand, she still needs something more helpful to help get her through the rough patches she's been through.

I look forward to discussing this, or hearing about anyone else's experiences with this and how it ended up for them. I want to try and mend my feelings about her so when I see her I am guaranteed not to break down, or feel too much guilt or unhappiness about the situation.
