Feeling terrible RANT

I really despise my baby father, he is a really disgusting person to me. His whole family is I dont even know what to call them without being rude. His grandmother is going around telling everyone that I'm expecting but yet has tried to get in contact with me like she doesn't have my number. Like why are you going around portraying this role like your this big good grandmother, his mother does the same. I left him when I first found out because he stated that my child was a mistake and that he didn't want it and that he would hate me for doing this to him.. At first I was thinking of getting a abortion because I was dumb then and thought that he was the love of my life until I really sat down and thought about it, why should I give a baby I want for a man or should I say boy who has done nothing but disrespect me and make me look dumb for years? So I left. I've tried calling and messages to let him know mom and baby are doing good but never got a reply so I stopped. And now so much has come to light, he has a new girlfriend lol I'm not mad or anything but I truthfully feel bad for her because all he's going to do is feed her with lies and probably get her pregnant too. I never wanted my child to be in the middle of all this disgusting drama.. I never wanted him to be my child's father either, I just feel like a terrible mother already and my son or daughter isn't even here yet.. I've been doing great alone without a man I've doing me and worrying about my little one and now all this drama is unfolding.. I just feel like a idiot.. I know my child will have a great mom but I don't want him or her to grow up feeling different or unwanted because it's just mom you know?
