Pregnant and want to leave boyfriend

Has anyone else ever been in a similar situation? I'm 15 weeks pregnant and want to leave my boyfriend and move back home. It's become an emotionally abusive relationship and I feel like I need to get out before or if it becomes physically abusive. I feel so alone and horrible for feeling like this is what I need to do and just need some reassurance. I haven't told my friends and family yet so here I am I guess.
