Unless his 3bet % is through the roof I think folding is really the only play here. We're drawing slim vs a big pair and aren't in great shape vs two overs with a spade. I don't expect too much more in his range except maybe some smaller pairs which are trying to protect against the draw.
Folding pf is an option, though I don't think it's a huge mistake not to. You're in position and are almost getting set mining odds
. Once we flat pf though your postflop line looks fine up to the turn.
