Should I pay for my sons college tuition?

He is 25 yrs old. I always told him if he wanted to go to college, I would pay the tuition. He met a girl, and she totally discouraged him from furthering his education, so he dropped out and started working full time. Well...the girlfriend dumped him and he came back home to live with me, and now wants to re enoll in college this fall. I expect him to work still, but wondering whether I should pay the books and tuition for him?
