Daughters dad

Just ranting but I absolutely hate my daughters biological father. We had contempt of court today because he hasn't paid child support and the entire time he made excuse after excuse for why he constantly gets fired, the judge asked him where he worked and he asked if he could not disclose that information and got pissed because he was told he had to. We were in there for about an hour and never once asked about or even brought up our child even when I brought up the counseling she received and the fact that she's in school now. He hasn't seen her in 2 years (she's only 3) and admitted to not having contact with us in that long. His only concerns were he was mad about me knowing his job and the fact that I knew he had yet another kid like are you serious? But he gets so mad when I refer to her as my daughter. You can't just abandon her and classify yourself as a dad. Sorry it's so long I just can't deal with this lunatic.
