$400nl: simple top pair type hand against probably bad player:i do bad

[snowbank]

Simple hand, but I play it poorly. Villan has like $338 in front of him and I've never seen him, so I assume he's a donk. I guess he could have a set here, but I can't really give up on the flop. Do I just fold the turn? Seems kinda weak if I do, but at the same time seems like bad line if I'm calling turn and folding to non-scary river. Sorry for simple hand, just think I misplayed it badly and feel weak just check/folding turn. Anyone bet/fold turn instead?
