relationship issues...

Hey ladies! So I need advise. I've been seeing this guy for a while, I wouldn't say we're " boyfriend/girlfriend". He's 6 years older than me and he has a 6 year old who is absolutely in love with me. Attached. Anyway, the relationship is great, but then he started drinking around me recently. He's not a nice drunk and becomes forceful and mean. Dosent remember it the next day. I'm so torn because he's a great man when he's not drinking, and his daughter has become so attached to me, but I can't be forced into sex, and called a bitch every night that he drinks. I'm so confused on what to do... 🙃🤷🏼‍♀️
