Is my ex BPD or a combination of things

[SurvivalGuy]

Hi all,

I am struggling with a breakup from ex (37f who I suspect has bpd) exactly 2 months ago and basically no contact for the last 5-6 weeks. I am blocked which I think is ultimately a good thing but I’m finding it hard to move on. I was on cloud 9 for most of our 6 months together. I keep blaming myself because she left me because I forgot to cook dinner. She said it was a trigger for her and it’s basically the same as me having an affair. The day before she sent me pictures of engagement rings she liked out of the blue. . I say suspect bpd but I’m not 100% sure. It would help me if I could figure out what exactly is wrong with her.  She has told me the following about her past but never told me of any mental illnesses:

- care giver role to family with mental disorders
- Mother with bipolar
- Sister with bipolar/anxiety
- Brother committed suicide
- Her dad was very harsh and hard on her
- went to boarding school (ballet school) and was raped and witnessed a suicide
- her ex partner was abusive and she has trauma from 15 years of domestic violence
- her kids left her for the dad
- she is hypersexual
- I always had to reassure her
- Very low self esteem

I am actually hurting a lot. Not sure why I can’t shake it off
