I don't know if this post is in the correct forum...If not, please do move it mods (thank you

).
Everything that I read is just pushing me. I'm scared!! Desperate and alone, I'm lost. I don't know what to do.
I was a member of a dating site and I met a guy a couple of weeks ago. He was very nice, polite, and he paid attention to me. We seemed to really hit it off, so we met several times within that time frame. Yesterday, I decided that I needed to be upfront with *Joe* about a couple of my big things: depression and my traumatic brain injury. (I didn't want to go into details yet) Joe was accepting of my admission and then decided that he should let me know about his ghost of the past.
Joe was frank and upfront.
Astounded, and triggered, I didn't know what to say. Somehow (for some reason), I asked questions to get a more clear understanding of what he had done. WHY?? I have no idea!
23!!! Here, I have many experiences of being abused. Emotionally, sexually, and physical. How could I take his side??! Yes, some people are wrongfully convicted of crimes. That's true. But, with my past, how could I possibly believe him??
UNBELIEVABLE that I was with this guy!!! I have ended the relationship, but I am now kicking myself so hard (I know, I absolutely deserve every little bit of pain). Triggered is an understatement. I don't know what to say or do. I've pulled away from co-workers and acquaintances that are concerned about me. I don't deserve their kindness. I don't know what to do.
