Turned my set, now do I fold? 100NL

[Dory]

Villain is 20/17/3 and seems reasonably solid. The only hand I have seen him show down, he raised A5o from the button, both blinds called. He checked behind flop and turn when he flopped trips. So I expect him to slowplay big hands to some extent.

My first decision was whether to raise the turn or not.
The board is really drawy, which is what led me to raise. But do I then fold to his push?

Apart from a combo draw, 44, or an overplayed two pair, I can't see much I beat. And I really felt like this was a str8.

So do I fold?
