stuck

I know this is really long but if someone could please read it and help me. I'm really not sure what to do or how to do it. I've been with my boyfriend for two years. We have a one year old son together and I just found out that I'm now pregnant again. Our story is so crazy and ridiculous. Basically long story short when I was pregnant he left me and started dating his high school teacher then came back and swore he changed and was just going through a bad time and was nervous from the big news. After that I forgave him and took him back but it was always in the back of my mind and I seemed to bring it up and throw it In his face a lot. A couple months later I found out that his "friend"which is also his ex girlfriends sister AND his bosses Ex fiancé he cheated on me multiple times with her and completely betrayed me.i know that if you take back a cheater you should know better but i was a week away from having our son and I was so confused I just forced myself to pretend it never happened. Months after my son was born we decided to move to Florida with his family to get away and start fresh with our new family. Things were really good in the beginning but then we started getting back into our old ways. I was getting really depressed and his family was always ganging up on me and he never defended me so I decided to move back home with my mom. I stayed for a few months and had no contact with him. We started talking one day and we both just agreed that we missed eachother and I once again moved back to Florida. We now have our own place and I can see we're both not happy. He gets mad at me over the littlest things and never wants to spend time with me. I've tried talking to him but it just causes more harm than good every time I try. I don't have a job and I have no family. I feel so stuck and I have no one who understands what I'm going through. I love him more than anything and I truly care about him but I know I deserve better and I think it's time for me to be happy. He never wants to be around me or do anything special or intimate. I'm just so unhappy and I feel so stuck. He pays for everything and always throw it in my face. Please some someone give me some advice or strand of hope. I know he's an asshole and I know I deserve better so please don't tell me things I already know
