😣😔😞😫😢😭😥😢

I've hit a point in my relationship where I'm not sure what to do anymore. the fights are getting worse and sometimes are still not forgotten about in the morning. the fights get very bad and when I cry about it I get the "oh here we go yeah start crying make me the bad guy" which only makes me cry more. I don't get to do the things I love anymore because he asks me to do something else with him. I got injured bad at my horse show so he took me to the hospital and promised to take me right home afterward. But guess where we went? A party for his enjoyment. I took him to a buddies for what he said and promised was only gonna be a smoke and then home for movies with me. No no no they offered him beer and he turned on me and made me the bad guy for reminding him he promised. he promised me yesterday he was walking down the road for a smoke and talk for half hour (8:30) with my guy best friend so I walked my dog down and no it's a party that he didn't want me to go to. The night before that he told me not to get ready because I'm not going to the party with him even tho it was at my friends house. his "boss" of whatever she tries to act as is only 2 years older than me and much prettier. He said he only had her number for work and now he has her on everything. If I did that I'd never be forgiven. he breaks many many promises to me it's safe for me to say he breaks them all. and when I call him out for how he's acting he looses it at me and I'm "pathetic" "selfish" "bitch" "never stop bitching" "physco" last night was the worst fight we ever had probably even worse than the time he cheated on me. we went to the party down the road that he said wasn't a party, we were supposed to leave at 8:30, I talked to my friends and let it slide. before he left he was being lovey and said he had a surprise for me when we got home. We left at 9 and got home. I laid there quietly gazing around and waiting for him to pay attention to me. He plays an episode of family guy and goes back to snap chatting who ever he was talking to. So I ask him "what's up babe, what's my surprise?" And he looses it at me. "Omg all you ever want is to fuck or have me eat u out" "we were just cuddling stop bugging or you're not getting anything" "not everything is about sex" "stop hounding me and watch the show" so I started crying silently because he'd get mad if I was upset. And I just needed to get out so I grab my keys and throw on clothes and he asks where I'm going. "For a drive" and he gets all mad and such and gets up and puts his clothes on all mad at me and says "go get the dog I'm leaving" (my dog growls at him and isn't too fond of him) and I said no and sat back down all in tears and anxiety, I tell him I need him because I feel a panic attack coming on and he gets mad and says I'm so dramatic and shit. So I take off as he runs out the door as well. He promised he wasn't walking back down to the party so I go for a drive alone and talk to my best friend over the phone to calm down and then drive back to where I thought he was. He saw me and ran, I followed. I got him to stop by my car for one minute just for me to ask him where he's going. and he no longer acted as my boyfriend he acted as if he had hated me my whole life, I didn't know what to do or how to react. not to mention the fact we might be pregnant. I still don't know what to do because I tried to wake him up for work this morning and he lost it at me again. I'm literally always stressed now. He lied about who he was with last night to make it even worse. someone please help me:(
