If your boyfriend did any of these what would be your next move?

So I been with my crazy ass boyfriend for a few months and lately he been doing some disrespectful and hurtful stuff to me but some people think im over reacting. So let me get in to the shit he has done. So two weeks into our relationship he looked up my record without my permission. Then calls me at work questioning me about everything that was on my record. So I let that one slide and few weeks after we get a pregnancy scared ( but this would be his first kid it would be the fourth for him but first for me after my last miscarriage) and he tells me if we are pregnant i need to get an abortion because we cant afford a kid right now because he has three kids. So whatever I didn’t pay mind to it because I was like I could do it on my own. Lucky the pregnancy test came out negative so thats one hurtle I jump through. But that same day at the doctors my doctor said I could have a heart or brain condition. I called him and he was no where. Call him the day after he picks up the phone talking about we should break up after i told him what the doctor said. But after hours arguing over the phone he called me another girl’s name (Cynthia which is the name of the mother of the kids) while my name is Selena. So what would you do if you were in my shoes?
