As they have said....the fines are going to be a lot more than the classes, plus potential for jail. He needs to take responsibility for this and contact the court asap.
I would advise seeking help with Community Mental Health or Planned Parenthood. You are already with two kids you can't afford and a third on the way. Both offer sliding-scale services for birth control. Michigan has a plan called Plan First, and I get my birth control for free. When I was employed, I got Depo Provera on a sliding-scale fee. It's a shot that lasts three months, and it was $40. Definitely worth looking into after your baby is born. Planned Parenthood can also assist you in getting supplies for the baby, and if you are being abused, refer you to assistance.
