Relationship rant

My boyfriend and I have been together for three years now. We are pregnant again with our first a boy, the other pregnancy ended in miscarriage with twins. We broke up after that for a little while and when we got back together he has been basically stuck me. I don't have a problen with it ecxept he treats me like i can't have any personal space or be myself. I use to do what i wanted when i wanted, but nothing bad or direspectful, just independently as myself. Now i can't even take our car to do things i want because he has to work ( he works really close to where i stay) and he always has a problem with it like i can never just have the car if i needed to do something or just wanted to. He says its where he takes his brakes and acts like its a big deal like a spoiled brat. He is used to getting his way from his family and im not for it. So today we got into it because of this and i haven't spoken to him and now he got a attitude because he feels so entitled to one even if he is wrong. I'm just sitting here thinking about how our relationship has changed and now i know why.
