Am I Wrong ????

So, I have a one year old and me and the father are no longer together. He also just recently moved to another state. So I’ve been on him about being there financially if he’s not here physically. Don’t get me wrong, I do have a job and I do take care of my bills and all of my son’s needs but being only 20 and living on my own things can get a little tight sometimes. I just want to know am I wrong for wanting and feeling like he needs to help because I didn’t make this baby on my own. I reached out to the family member he’s staying with about it because she seems like the only person he listens to. And she basically said don’t worry about him. Do your part. Like hoe that’s the whole point I am doing my part, he’s not doing his. I’m pissed
