He moved out on me and our daughter what should i do?

To kinda of make it short. WE have been together for 5 years, we never really had that getting to know each other time because we got pregnant, had our daughter. He did cheat on me and told me he fell in love with this girl because they had everything we didn't.. 2 yrs later we moved to Fl together, came back, hes got annuity and than when we came back from Fl after him not being able to open up his own business and said we'd go back in 2 years to try.. he smacks me in the face that he talked to that girl from 3 years ago for advice and i dk what she told him, BUT he says now, he needs space,we're 2 different people, Im immature(which im not believe me) i mean i can be childish in certain ways, BUT im really really hurt, we have a kid and he moved out? he has sooo much money and he asks me for money? he tells me he needs time because i need to mature and be able to do things for myself since i depended on him and that i need to be alone more to figure that out. THAN he tells me i can stay over there with him and the baby(no sex) and we watch movies, go out to eat. I JUST DONT GET IT. than when i invite him to do something for us as he puts it "GET that dating part of our rel that we missed" its like he tells me again, he doesnt want me to ask him out and than i get mad and he calls me selfish.He tells me to get a life because it gonna take time to fix it and he gets annoyed when i bring it up cus its only been a few weeks? dont you think we'd work on it for our family right away? but he said he's not going to fake anything. I told him i loved him, i asked if he did after he said he hated me, he said no, that he just said that than he loves me.? I DONT GET IT.hes 26 isnt he childish? im trying to hold on to my family. i dont know what to do? i mean if it doesnt work out, yes i will go for custody and child support because those are just another issue on his careless part, but this isnt the man that i was with for 5 years??? help anyone!!
