My sons father doesn't help

Since I found out I was pregnant my sons father never did anything, he didn't even bring dollar wipes or anything. He manages to hit me up on snapchat to see how my son doing I'm due January 7th. I hate him with a passion and he doesn't understand that. Wednesday he FaceTime me asking me what he needs n etc I said I need $200 and he gave me so many excuses on Friday of why he couldn't. I EVEN SAID ILL COME TO YOU. I honestly don't want him at the hospital when I give birth. I just want him to come by n sign that birth certificate truthfully! Am I wrong for only wanting that?
