Idiot in Ex Life

I'm irritated. When I met my ex he said all the right things, sang all the right songs. I want to have a baby. I could never imagine not seeing my child everyday! blah blah blah. After I put the idiot through school and supported him for 2 years, kept a roof over his head, food in his belly, and gave him a child, he finished school and said see ya around! He hasn't seen our son in over 2 years now. Calls him every 6 months or so. Never sends him so much as a b day card. Now he has been ordered by the court to pay child support starting this year. Which he never bothered to pay the last 2 years. So what does he do? Quits his job since they are taking it out of his check. Classy. Loser.
