I need help

Hi ladies. I feel like I’m going to explode at any minute. I’m so lost and confused. I jumped into this relationship very quickly after a bad one ended. It wasn’t necessarily a rebound but some would call it that. It began fun and great. Although he had another relationship going on. Then things took a bit of a turn. He became extremely demanding and controlling. Like wanted me to get rid of friends, stop talking to men at work, only wear certain clothes around him and so on. My last relationship was like that in a way too. He’s said he wants to marry me and have kids. I’m 36 now and kids are out of the question. I’ve told him I didn’t want to do any of that. I don’t want to be that committed anymore. He now wants to sell his house, but a travel trailer, park it on my land until he can buy his own then have us build a house. I’ve told him I’m not ready for that. I’m so tired of being controlled. I’m tired of being treated like a 3 year old. He gets mad at me when a man speaks to me, like I can help it. He wants me to have this amazing self esteem but I’m not allowed to look or talk to other men and I’m not talking about flirting I’m talking about saying hello back to an old acquaintance in passing at the gym, makes him angry. I cannot be me at all anymore. The moment something is wrong and he asks and I get the courage to actually say whats on my mind, if at all negative he gets angry. Then I’m like why do I even say anything if it’s going to get me in trouble. I’ve tried to break up with him twice in the last month and over our two years I’ve tried at like 5 times and he always makes me feel guilty for it so I come back. So I’ve gotten to the point where I’m just going to bow down to everything he asks. I can’t seem to make him go away and he refuses to let me go. I don’t know what kind of help I’m asking for bc I realize I’m in this position but maybe just some women input seeing as how I have no one in my life but him now.
