Mutual Friends keep defending her to me, but I'm done with it

My ex girlfriend had BPD. And well, she screwed with my head so much to the point I had a nervous breakdown. And she turned our two mutual friends against me.

Now luckily I had physical proof about what she was doing to me, so I screenshotted the texts (She didn't think I would do that) and sent it as proof.

Sadly, they still were like 'Oh, but she's having a hard time, she didn't mean it, you have to understand she's been through a lot'

They completely downplayed what she put me through and when she started therapy allegedly she was making 'realizations' about how much abuse she went through.

But the sad part is I don't believe her anymore, I know BPD has to be caused by something traumatic in the past. But the fact that she's done a complete 180 about her life story is just so jarring that I think its a bunch of BS.

It also doesn't help that my former mutual friends keep enabling her behavior. She's been unemployed for nearly a year now, has her car and bills paid by them for her. She doesn't contribute anything to the friendship other than them dealing with her split episodes.

They even tried to VENT to me about how stressful it is for them to be dealing with her bills and her car payments while she gets back on her feet.

Sometimes I think I'm crazy because 'How did I tolerate this kind of behavior and toxicity for so long from her?'

If this was before her split episode, I would probably be trying to comfort her and letting her know I wasn't going anywhere. But because the person I dated and the person who dumped me were two completely different people. Heres what I think.

1. When my friends confronted her on what she was doing, she realized she needed to say something happened to her to gain sympathy before they kicked her out

2. She may have gone through this traumatic stuff but not nearly to the same extent as she said

3. The only reason she hasn't hoovered me is because she's getting her new high from the two mutual friends

4. Despite going to therapy, I think she learned just enough to mask everything, because no way someone gets better from BPD after only 8 months of DBT
