For Anyone Who Has Ever Been Abused Only….?

I am a drug addict and my boyfriend of 5 months is one as well. We both use methamphetamine daily and occasionally will quit for 3-4 days at the most. I’m not bragging in any way, in fact, this is very difficult for me to share, but I have no friends, as the meth has pretty much ruined that aspect of my life. I know that I need help, yet I haven’t been seeking very hard. My boyfriend is abusive at times. I’ve always been the person to advise my friends to leave a relationship if there was ever abuse and now I see myself in their shoes. Why is it so hard to leave when someone is hitting you? I know that its wrong, yet I can’t seem to get away. Has anyone else ever been in this situation? How did you get out? I don’t want to be alone. Maybe I just need someone to talk to. I just need to hear someone elses opinion on this. Thanks.
