Getting pregnant and the age of 15, by an 18 year old, would it Ben more likely for me to get custody, where I was not pegal age to consult?

I was 15, he was 18. I am now 16, and he is 19. He wanted nothing to do with me or her until I court ordered him to take a DNA test and it came back positive. Now he wants her in his life so he doesn't have to pay child support. He harassed me in the last 6 months of my pregnancy saying I was a whore and she isn't his, wh n she was born I asked him to try working things out with me so we did try for about a month or so, he would come over just to sleep at my house then leave. He would ask to go out without our daughter and he wouldn't come see her for 6 weeks at a time. He has NEVER bought her a single thing and thinks he is a more fit parent than me because he is older. He smokes weed and drinks a lot and in all honesty, with his past and him being with girls younger than myself, I feel like my daughter is in risk of being hurt. I don't want to keep her from him, I ask him to come see her but recently he told me to never contact him again. Until my mother got a message from him.
