Do they lie about all of their trauma?

I believe a lot of what my expwBPD told me is somewhat true but many of the things she said turned out to have either never happened or had happened differently then originally told. Most of the stories had similar patterns and by the time I discovered most of the truth I feel like their trauma isn’t justified enough for them to be put in this „abused“ position. One of her ex partners I actually spoke to. He told me about many incidents of her actually abusing him. Believe it or not but the stories that he told me she actually told me the exact same way but the other way around as if he was the one who did it to her. The question is, what else did they lie about ?

When speaking to her directly about the lying she told me that she was desperate for the attention and thought that people wouldn’t find her interesting enough to give her attention if she doesn’t exaggerate the stories. It’s not only about the trauma, it’s also about small little stories throughout the day. For example she was talking to her siblings about the jacket she had on. The siblings loved the jacket and she told them that the jacket is really expensive so sadly she can’t lend it to them. They asked how much it costs and she told them it was $100 even though it cost $50. Random small lies while telling stories was like her morning breakfast. She did it everyday.

Do they all exaggerate their trauma?
