Need advice, kinda going outta my mind...

Okay well I'm 22 years old mother & wife.. Ive been breaking my head trying to figure out how to make a decision. So my husband & I have been on one hell of a roller coaster for the past 3 years. He gave me the biggest blessing ever. Which is my beautiful daughter Olivia Marie. My daughter was born with hydrocephalus so I spent almost 4 months in the hospital since the day she was born. Now ever since she was born or better yet ever since I found out I was pregnant my husband would leave to work & not come home until he was done "hanging out"... Now when my daughter was in the hospital he would never want to spend the night with us because he wanted to "sleep in his own bed"

So I was always alone with my daughter. 😒my daughter got surgery and he didn't even wanna be there then... Time goes by and I catch him cheating on me. I of course forgave him because I truly could not be with out him because of everything I was going through with my daughter. As the year goes by nothing had gotten better.. We were always arguing and are still arguing. I feel afraid to leave him & it always makes me feel stupid for staying but I don't know how to let go. I feel like I need him because I'm just so used to being with him, it's really sad because I want to leave him but I'm afraid. Now when we argue he get physical with me & he'll break my car or something he knows will bother me. My daughter doesn't like to be with him, she cries histairically when I leave her with him. Really sad because that's her dad.. I don't know what to do with my life. I want to move out but I don't know how to tell him I don't wanna be with him anymore. Please advice anyone... Thank you
