I’m sorry if this isn’t the place for this, but I’m lost. 

My (20F) now ex boyfriend (25M) had a manic episode in September. After violent outbursts and eventually being arrested, he was placed into a psychiatric ward where he received treatment. While he was inpatient, he began a relationship with another girl. This relationship continued even after he got out. He was violent with her, and she eventually left. My ex wants forgiveness, but honestly he hurt me mentally and threatened physical harm upon me while he was manic. He says I’m a bad person for wanting an apology for his actions. He said I shouldn’t ever be a nurse, and that hurt. I suffer from different mental illnesses, so I never will pretend to understand what he’s been going through. Is his mania and excuse for not giving an apology?

Honest opinions please. I just want to try and understand him. Sorry if this is rambling, I’m just really upset and confused.
