I'm so sorry for all you've been through.
I would encourage you to leave the boyfriend. He's not in the least bit supportive
and you need and deserve someone who is. You need time to heal before you can think
about being with someone.
Where I live, there are free counseling centers for people who have been abused or raped.
Maybe you could go to someone like that? I told my mom I was going to do volunteer work...so I didn't have to tell her what I was really doing. Maybe then they could drive you, or a friend's parent?
But either way, the boy has got to go. You're too good for him.
