AA against dumb weak guy, maybe non-standard

[steaknshake925]

villain is weak and seems to bet the strength of his hand. he'll call decent sized bets with TPshittyK type hands on dry boards, and i dont think he bluffs. basically he's the dumb weak type that instead of checking his weak hands he'll bet like $4 into a $100 pot.

party 3/6 6max
i have AA on button, villain is EP, stacks 600 each.
villain limps, i make it 22, villain calls.

flop 7d 9h Td
villain bets $15, i raise to $55, he calls.

turn Jh (pot ~160)
villain bets $25, i call.

river 5c (pot 210)
villain bets $25 again, i push

like?
