Idk what to do

Ok so I’m in a relationship with this guy his a bit selfish/self centered I guess u can say idk:/ but lately he’s been wanting a baby and when I told him I didn’t want one and I wanted to use protection he asked why and a million questions with that why and what I mean by selfish and self centered is he doesn’t have kids he has my two kids but he’s acting like if he pays for everything but he doesn’t I pay my part of everything we split rent and bills I buy my kids there stuff not him onless he randomly buys diapers without me asking he always comes home mad from work and takes it out on everyone else there was a day where his nephew and my friend were here his nephew is our roommate but he hardly sleeps over and I was sad I’ve been depressed lately idk and I was in our room sleeping on “his side” of the bed and they said they were playing with my kids in the living room he went storming out there complaining that I was sleeping on his side of the bed my daughter was pooped and he yelled at her telling her to hurry up and they looked at him like wtf cause she’s only two there’s times when he’s mad and he will be like I just changed u and u already pooped again like if she knew how to clean hurdled I’m sure she would she’s only two he took out a Jeep under his name but I paid the down payment I pay the insurance and I pay the monthly payments he pays none of my bills and he always rubs it in my face that technically it’s under his name like hello tell me something I don’t know I told u to put it under ur name and for Father’s Day I had to work but we were having an event so I told him come celebrate it with me and the kids u can bring ur grill and u can cook the food while spending time with us he didn’t complain to me but to everyone else that this was not the way he wanted to spend his Father’s Day he’s a his way or no way type of guy his ex wife had money so he was spoiled which I knew obviously he’s had shit handed to him Majority of the type if not by his parents then his ex wife but he does work he’s a corrections officer I don’t remember the topic but he started telling me I was expensive and I looked at him like u don’t buy me anything i don’t even buy myself stuff the clothes I hav are years old if anyone’s expensive u are and he didn’t argue he just shut up he went outside and asked my friend who’s more expensive me or her and she’s like u obviously look at ur new grill and ur truck and he’s like what about her Jeep and she told him u didn’t pay for it and ur not paying for it she is Amherst shut up got a little mad and didn’t say anything and he is expensive I bought him a 600$ iPhone cause he wanted one like mine I got him a 700$ tv for his graduation gift cause he wouldn’t stop bitching I got him a small 60$ leather wallet that he didn’t even appreciate cause it wasn’t a check wallet so for Father’s Day I got him the one he wanted another 60$ and he complained cause he didn’t want a wallet he wanted a gun! A fucking gun! I’m sorry this post is sooo long but I feel sad stuck and alone and I have always had the mentality of if I feel alone with someone then why am I here the kids are not his and we have only been dating 7 months and I feel stuck I need someone to please talk to me the main reason I feel stuck is cause I have no where to go my family lives in Texas and I have no relatives here (Georgia)
