Can I get away from top 2 pair here?

[DrewDevil]

Live 2/5 NL game. I have about $250 when the action starts.

UTG+2 raises to $20, MP calls, I call in BB with KT off.

Flop K x x. I check, checks around.

Turn is 10, giving me top 2. I bet $40, UTG+2 calls, MP folds.

River a blank. No flush is out there, and no straight, really, except like a 4-7 or something else weird.

I bet $100, leaving me $105 behind. UTG+2 thinks a minute, then goes all in, he has me covered easily.

I feel sick but I don't think I can fold here. It's $105 to win $445.
