Me sleep talking.. Becoming a huge issue.

So, apparently when I'm asleep and my fiance is awake I'm a total bitch to him. I absolutely have NO memory of saying rude things to him. I talk in my sleep and a completely different person. Eyes open and everything, I'm actually asleep. My mom and grandma knows I've always talked in my sleep with my eyes open. I wake up and he's pissed at me like every day, cause of what I said in my sleep to him. Ill say things like 'get off of me'. I punched him in the face and gave him a nose bleed for touching my nose in my sleep. I'm not a mean or violent person at all and I feel terrible that I can't stop it. I can't control it from happening and he gets pissed off that I don't remember anything I did or said. I can't help it. I get mad at myself. He said I can't get mad at him, and I told him I don't control it. What do I do. :/ this is a every day thing and it might be weird, judge me it's fine but it's causing issues in my relationship and I don't need the stress while I'm pregnant and need advice.
