Trip aces in a tough spot, easy fold?

I need a read to make this call, and a lot of the times I do. Looks like he's afraid of the third spade with his trips.

I hate the pf raise, your hand is speculative, and can flop big and stack somebody, you're cutting your implied odds and shutting out hands that you would be ahead of on flop like this. Save that move for a hand that flops one pair well, (does well heads up).
