micro limits, villain is 14%vpip and 3%pfr but when he plays a hand, he bets it aggressive postflop.

2 people (including me) limp to the villain, who minraises. He rarely played a hand, and nearly never raised preflop and to me this just screamed he had a big hand and wanted some money in but not lose everyone...I actually put him on aces preflop.
I had seen a few players do the same in a situation like this and it nearly always was KK or AA.

I held QTs and called because I figuered since I (at the time) was rather sure I knew what he held, I wanted to see a flop.

Flop comes A T Q different suites, giving me 2 pair. I still believed villain had aces but wasnt willing to lay the hand down here if he makes it cheap. He raised about 1/3 the pot and I called.
Turn came an harmless 8. He bet rather weak again (~1/3) and I called.
River came another Queen giving me a full house. But aces would get the better fh and so would AQ.
He pushed, I pondered and...folded.

Any thoughts on the hand? Bad fold? Fold earlier with the read?
I really feel like he had aces, but still...

Edit: actually I think I reraised his flop bet and he called.
