Can he get away without paying child support if he is jobless and fleas the state?

My boyfriend of 6 years is moving to go to college to get away from the responsibility of being a father. He wanted our son and suddenly changed his mind. His family also wanted me to get an abortion and are now saying they will try to get full custody when the baby is born because they don't think I'll be a fit parent. He is 21 years old and won't have a job up there; he will be a full time student. I will be filing for a paternity test once our son is born and working with the department of revenue. Although, since he will be gone, how do I get him to be tested? Will the state make him? Will it have to be court ordered? Also, can he give up his rights to the child? He is obviously an unfit parent since he is fleeing, but would that make the judge terminate his rights if he asked? I'm just worried he's going to get away with all of this.
