The world is full of dead beat dads and moms. You should be upset but you shouldn’t dwell on it. Your child is better off with a parent who loves them and takes care of them, even if it is only one parent. A person who knows he has a child and still doesn’t care doesn’t deserve the joy that being a parent brings. I have kids and I love it. I also love having a good time and partying. I do both things…Responsibly… Someone who can’t be a parent and be themselves too needs to stop having sex or get themselves spayed or neutered.
