I sat down and talked with my abusive partner.
What made you decide to talk to him?
I don't want to be hysterical about this issue, I'm a flexible person.
That must have been a difficult conversation to have.  It shows strength on your part to try and work through this issue with him.  I hope you two find happiness!
I'm not sure if it's going to work out because he was very angry. I'm trying to be optimistic though.
It's possible that it won't work out, and that's okay. The important thing is that you tried to talk to him about the issue and resolve it. If he doesn't want to change then it's his problem, and you shouldn't feel bad about leaving him.
