10NL Flop a set and river completes 4-card straight

[finalboarder]

Villian is running 50/10/4.

Villian was betting almost every card. So the reason I didn't bet out on the flop and turn is because I wanted him to put the money in. My reasoning was that he would do this with hands that he might otherwise fold if I was first to bet. On the turn I think I should have made my reraise a big larger, I guess I was scared of him folding. When he calls I am not really sure what to put him on. Before I thought that he might have a T. Then on the river I have no clue what to do any hand that has an A in it now has a straight. Should I check/fold?
