Minimizing losses from the blinds

I'll let you in on a little secret: I don't like it when people attack my blind.

I know this is the case for a lot of players, but I probably lose way more money from the blinds than I should due to the fact that I never give a player any credit once I've made up my mind that I'm up against a steal attempt.

I had such a blow-up earlier today when I dropped a whole buy-in at a $.25/$.50 NL cash game on UltimateBet. The player to my right had only been at the table for about a dozen hands, but I had already tabbed him for an aggressive player who liked to make moves after the flop:

Abdul_Akhmed wins $58.40 with two pair, kings and tens.

I decided that he was trying to buy the pot after he insta-bet the flop, but I really should've slowed down once he reraised me, especially since I didn't have a large enough stack to push back with on later streets.

The worst part is that he probably decided to slow-play his KK specifically since he had seen me aggressively attacking weakness in the few hands prior. He set the trap and I fell right in.

I know that it's important to trust your instincts, but I didn't take any time to re-evaluate my initial read as the hand progressed because I was too preoccupied with defending my blind. I don't have these blow-ups too often, but I'm sure the losses will add up if I don't learn to let go from time to time.
