To the people who are saying that it's weird she brought up her "past trauma" on the first date, I would just like to add that as a survivor of childhood trauma, it's definitely not out of the norm. If I was going on a date, I would explain that first just to get it out of the way. I wouldn't want to be a burden to someone who couldn't support me. The details and shit coming first, that's strange for sure and a warning sort of thing, because usually, trauma victims have to be very, very close to a person to be able to tell them all these details.
I realize she was lying, and it's great that OP is able to get out of this relationship, but I just wanted to say that people revealing any mental illness they might have that severely affects their life isn't necessarily a warning sign.
