I'm so lost...

UPDATE !! 
 My boyfriend and I are going to therapy. We're gonna go once every two weeks together, then separate. We eventually are going to ask my mom to accompany us on one of our sessions so she can see we are trying to make progress and restore our relationship. 
Warning ⚠️ this is kinda long and me ranting. But I could really use some advice. 
So recently my boyfriend and I got into a bad argument. It escalated to us being outside and me screaming in his face. He kept asking me to get off of him and I wouldn't. He finally pushed me off of him and walked away. The push didn't hurt me but I was so mad so I ran after him. Long story short, my mom ended up seeing him push me. (We have survalance cameras outside) and she's still fuming about it. Him and I have talked and are working it out. But my mom doesn't want anything to do with him. Him and I have never been physically abusive towards each other and never even called each other out of name. This is the man I'm going to marry but I'm so torn because I feel like I have to choose between him and my mom.
