Call the turn. Donk a river 2. Check-raise a river Q. Check-call everything else.

We don't know enough about button to fold here confidently. You raised pre-flop and he raised the flop, and those things seem to eliminate a lot of the things that may be beating you. It's a set I'm worried about, maybe something like 76s. But a lot of players with his profile don't raise the flop if they hit a set. And he could be aggressive enough to be overplaying 88, 99, or something.

Folding now will also do bad things for your image. Folding 20 straight hands and then check-raise/folding the first hand you play will look very weak and might compromise some potential in an otherwise good game. That's a small consideration certainly, but makes me feel a bit better about a loosish call down.
