KQo 5/10 limit Raise from UTG + 3

[aes14]

I have a quick question. I was playing 5/10 limit and a raise came to me from UTG + 3 and I am MP. 10 seats.

I folded KQo to the raise. Should I have re raised and taken a look?

Hindsight is 20/20 but the raiser had TT and there was a re raiser on the buttom with ATo. Board made all spades and my Qs would have been the winner.

Was I right to fold here or is it a re raise?

Thanks!
