what should i do? help

So here goes I live in New York and I want to know how the child support works. My bf who thinks he a good dad just because he give me 60$ once in a blue to go buy baby clothes or Watever is enough. Since I was pregnant he's treated me like shit and I stayed thinking he would grow up but it's still the same. He wanted to renovate my parents basement  so he did so that we all didn't have to live in a shitty place with our daughter and I have left work since I was 5 months pregnant and my daughter is about to be 5 months. Now all we do is fight about money and because of the renovations he didn't have all the money so I asked my sister to help me out which she was kind enough to do because his family didn't want to help out at all. The total amount came out to 6000$ the guy said and then little by little it went higher and higher to get a counter top for the kitchen and cabinets my sister and him said they would half each . My sister thinking at the time meant half so she put half and because there was more expensives like material that's when I asked her to lend me money because my be didn't have enough at the time. So now it came out to total 11,000$ renovating my basement and I wanted it all done before the baby got here but he didn't want that he wanted to bring a baby home with a home that wasn't done it was still dusty and I didn't want to live like that. So till now he owes my sister 4000$ but he kept asking me if she could lower it down so she did to 3000$. Mind you everything was done in my taste not her and on top of that after the baby was born she help me get 1000$ worth of thing for my daughter because he didn't want to pay for it now. So now I'm done with arguing all the time I've fought with to try and stay together as family but all he wants to do is hangout see his family 24:7 complain that' he's the only one working and he has to pay for everything and that I wanted the baby do I have to take care of her. I'm done with it I've tried my best to keep my small family together but I can't anymore. He's never there for her he doesn't changed her diapers he's never changed her clothes he's never taken her shower he's never put her to sleep and he's never held for more than an 45minutes . All his free time he occupys it with friends or going to six flags with cousins instead of spending time with me and his daughter. His family doesn't even come around to her because he's spoken so much shit about me that they don't want to be around me. They send him text saying send me pictures of her and I don't agree with that. He says I'm the one to blame for everything that i waste his money to much that my family is inconsiderate. We pay for no water no electricity no food just 350$ rent for a huge basement to live in and they bought us a portable AC THAT cost 600$ and my family is in considerate. For my baby shower they didn't want to help they gave us 200$ and that was it his sister gave her first niece a doll that's 20$ and she makes good money . This entire time my sister has been the one helping me out taking care of daughter when I need some alone time for an 1hr or 2 if family doesn't offer me shit nor call me or ask me how I'm doing. So where I'm getting at is I want to collect child support from him but I don't want a father like that for my daughter who just want to see her what 30min a day every 2days. Would that matter I don't want his family nor him involved in my daughter life since they don't even care now I won't give them a satisfaction to want to be with her now because I want to claim support. He says he loves her but hell of way that he shows it to her by not seeing her. Please feel free for your opinions and what I should do about child support.
