Recently had a pretty big falling out with ex gf of several months and great friend. The story is very convoluted and confusing, so please try not to judge me for my actions and let me know if you have a (useful) idea of what's going on in her head.

I have been doing much reading lately on bipolar and BPD. She has several existent psych issues, and I want to know if she fits into this category.

Her: 21/f.

We dated for a little over a year, and had I not known her so well and her issues, I would've run. So here I am.

She has self diagnosed (and somewhat obvious) OCD and anxiety disorders. She was abused sexually by a family member at around the age of five to eight. She was raped at the age of 13 by a much older guy at a party, for which she received therapy, but her father is still of the mindset that she was "asking for it." Since that time and when I met her (we were about 16), she has been very promiscuous, gotten into a physical altercation with her father, and since moved back in with him and her family.

She has frequent panic attacks and bouts of extreme depression. She absolutely cannot compartmentalize and allows things to pile up until she freaks out. She is constantly the victim in most situations, everyone hates her or loves her depending on the day, including me...at least from her perspective.

During our romantic relationship, she was constantly rapturously happy or horribly angry or sad about us. The instant I did something wrong, she was yelling and verbally abusive, until I did something to calm her down. Then she loved me again. When she couldn't be consoled, she would talk suggestively to other guys, and during one of our "breakups" she had sex with another guy. We have very different views on sex obviously, but she uses it as a weapon, and views it as next to meaningless.

Don't get me wrong, when things were good, they were great. We were best friends for years before and during our dating times, and this is much of the reason I stuck around so long. She always referred to me as the "only constant in her life," and for this I felt an extreme responsibility to protect her from herself.

We finally broke up pretty suddenly back in march, and by April she had a new guy, and they were pretty "serious." By late may/early June she wanted to talk to me, tell me how bad things were with this guy and that we should be friends again. I know her, so I know what's going on here. But my heart got the best of me. We hooked up some, hung out and were best friends.

The same things kept popping up. Back and forth, promiscuousness, anxiety, anger. Now she has a new guy, who was nice to her and let her take care of him, and now she's "happy." Most would say, good riddance, dodged a bullet, etc, and you would be right. I don't want to date her anymore, but as a friend, I have to know because I know these decisions are going to continue to pile up.

Does she show signs of BD or BPD? If you want to line up symptoms, I can elaborate on specifics, but I know this is already really long. 

Thanks so much for some educated opinions.
