Am I crazy or...

So I starting dating a guy very handsome, good job, a little controlling for my taste but I took it a day at a time and was planning to wait and sort of see his true colors. After dating only 3 weeks he told me he was in love with me, odd I was just kind of flattered though and didnt look too much into it. We started having sex. I didnt take birth control bc it always made me sick and I wasn't having sex often up until this point so it seemed unnecessary to me. He had just gotten out of a two year relationship in which he said he had always had sex unprotected and been fine as far as avoiding pregnancy, he explained that she had no reproductive issues and that he works around chemicals and it is common for the guys in his field to lose their fertility. We're young and I wasn't looking to have kids so this fact didnt bother me, but I trusted him with no reason not to and took it as a fact. Just to sort of be extra in my mind I had him pull out always. Three months later I get pregnant in a very new relationship.I hate the idea of abortion and he has a stable job so I let the baby and we talked and he acted shocked as if it was some kind of miracle. I just assumed it was an honest accident and that he didnt purposely misinform me and moved on. After a couple more months of dating and being talked to by my traditional parents we got married "better life for the baby sort of thing" now he has gotten more controlling. Controls money, made me delete social media, asks me where I am all the time and looks at my location, goes through my phone, calls me dumb slutty and criticized my cooking folding etc that I sweetly do for him. I now think his insecure irratic behavior may be a pattern I also have sort of an instinct that the pregnancy was intentional a trap me and have that control over me sort of thing. I am now about half way through my second trimester and feel sort of lost in this situation. Any suggestions...
