(NL50) Turned two pair meets aggression

[PietM]

Villain was loose (50/17/1 over 50 hands). Pre-flop is not good, I guess. I wanted to raise more on the flop (to $6) but misclicked.

What can I make of his push on the turn? Seeing the hand now it looks like a big pair (AA/KK/QQ) more than anything that beats me, right?
