$1/ $2 NL 6 max

I raise $7 with [Kd]. Button calls.

Pot $17. Flop [5d][3c]. I bet $15 and he calls.
Pot $47. Turn . I bet $40. He pushes all in. Its $130 more to me. Easy fold?

The more I think about it, "getting away from an overpair" is a mistake for 100BB without a read that your opponent is super nitty.

I would probably fold without a read. Turn is where few people actually make moves so unless he is aggro/donkish enough to play 9x TT there that aggressively i don't see what hand he can have. Sets/turned sets are possible, 76 had double gutter and got there, while if he has backdoor diamons he most likely has at least pair+ diamond draw with most sc there. 54 is also possible but not great part of his range. I think that this is rarely air so its basically a made hand better than ours or backdoor draw that should be decent.
This applies only if opponent is somewhat decent

I tend to agree with gsdavid. The flop was dry and sets will feel comfortable slowplaying, but this turn makes the board pretty wet so I can see a shove from a number of better hands. Plus, the only draw got there.

Still, I don't think this is clear cut or an easy fold and I would definitely call here a lot because I am a station.
