I 19F have been dating my boyfriend (19M) for about 2 years I think, we’ve dated on and off multiple times because he’s cheated on me about 12 or more times. I know thats horrible to say and I don’t know why I stayed so long but I’ve become so dependent on him. I spent all my savings moving into an apartment that I didn’t realize would be way too expensive for me to handle with him about 7 months ago. I’ve bought 99% of everything in the house so I can’t just up and leave and I can’t afford rent on my own. He doesn’t treat me well sometimes but I think I just hold onto the times he does treat me good. He buys me food all the time, he lets me borrow his car and helps me money wise when I need it. But other days he’s rude and stuck up, he plays too rough when I’m just joking around or trying to be funny, he’s threatened me before saying that he’d hurt me but I don’t know if i should believe him. I have a 2 year old daughter that isn’t his but he helps me take care of her for the week that she’s here and she loves him. I’ve destroyed my mental health to stay with him but he’s spent so much money and time on me that I feel like I can’t. I want to move states when my lease is up but I don’t know how to tell him I don’t want him to come with.

Sorry I know that was a lot of context that probably doesn’t make sense but I have no clue on how to get out of this relationship without feeling horrible?
