Confused and upset :(

So im 24 and have been in a 2 year relationship currently in 10weeks pregnant and so excited for this baby but not too happy with my relationship. My SO has cheated and lied in the past i can say that for the last year he has changed alot and i have no actual reasons to think hes cheating or even talking to anyone, he no longer has passwords on his phone and he tried to have better communication  but the trust is not all there. I became insecure and sometimes i can feel like the women he cheated with will always be better than me. I trully thought things were better and i do see a change in him but since we found out i was pregnant he started acting as if he owns me, hes tried telling me what to wear , at this point i have avoided argument so we dont end up fighting but I believe it gave him "power" over me and he makes me feel unappreciated , he starting going out with coworkers on the weekends he states its only guys but i cant do the same with my girl friends? Finally a few days ago i exploded and went off , i let him know i was getting tired of him mistreating me and disrespecting me , i work full time and take care of our home to make sure his clothes are clean and there is food on the table when hes home and hes acting single he cant even let me know where hes going sometimes. I told him these actions are making me doubt him again and he told me to stop putting shit in my own head!
