I never got to explain what really upset me in detail,
This post will be triggering, so please don't read if CSA bothers you.
Hopefully soon this thread will have a trigger warning.

Anyway.
A lot of memories of an abusive relationship I was in came up when my abusive ex tried to get back in contact with me. I was 15 when we started dating and he was 25. He was physically abusive and sexually abusive. I had to call the police on him at one point because the abuse got so bad. I felt really messed up by him asking to get back together because I had literally forgotten all about him until he wrote me again. I'm upset at him for being so selfish. Then I didn't know what to do about him so I talked to someone I considered to be a friend who is married and in their twenties. They seemingly ignored me and started asking me for advice on his sexual relationship with his wife, despite all the times I tell him I have no sexual experience with anyone except those experiences that were abusive. (Such as being raped and sexually abused by my uncle for a while, and then The sexual abuse from the bad relationship.) Then other things like work just elevated my feelings of anger towards adults.
I was hurt by that and he kept triggering my PTSD. That was what really caused me to get so angry. I came here because I felt like people would try to help me. I felt like people here would understand.

I didn't mean to make anyone feel bad, I was feeling bad myself.
