Am I being sexually assaulted by my boyfriend?

so last night I was in a heavily deep sleep and didn’t ask my boyfriend to do anything he did to me. I won’t get into the graphics but if I was asleep and I didn’t want anything that happened to me but was so weak and didn't want anything of it but I tried to communicate that with him but cover my breast and privates asking him to stop the best I could I even tried fighting back and saying no but I was just so weak. He held my arms and hands down so I couldn’t fight back.

He told me he’s been trying to get better with the sexual stuff because he always ask for it he did get better and then last night he did that and I kinda remember but am a bit confused and lost and kinda hurt I’m scared to speak to him about it because I know he will make excuses and cry and act like he didn’t mean to hurt me but he’s repeatedly hurt me several times now in the past I would tell him no but he would always take his arm and choke me out with it and make me tell him that I did want it but in reality I did. I’ve tried fighting back but I’m no where near as strong as him. He knows I’ve been hurt in the past and sexually assaulted and abused by past boyfriends because I though I could trust him. But I feel like being used. I am scared to break up with him because I do fear him and how he acts he’s very manipulative and very mean.

I don’t know what to do. Is that sexual assault or harassment or am I overthinking and overreacting? I’m lost hurt and confused. I feel so dumb and just I don't know. It all is hurting me because I trusted him so many times to not hurt me but I always cry in the end and he was always dismissive of that and said I was the problem because I become distant from him and it hurts him. He also always tries to grab my breast and I hit his hands and have even kicked him between his legs to get him off or get him to stop and he says I’m mean and rude towards him…. what should I do?

Ok…so this morning I grabbed a trash bag and filled it with as many things of mine as I could after his dad and him left for work so I’m headed off to a new home in a totally different town than the closest one to them. I’ll be in a hotel and hope to find safety and get some help later from a therapist if insurance will cover. Thank you everyone for convincing me to find a way out I’ve been so scared but I felt reassured that I would be ok with leaving.
