help me play this better

[montechristo]

5/10 NL eff. stacks 800

Villain is pretty good LAG, usually shows
down the nuts but is tricky, more than capable of making moves. He views me as Laggish, not having a good day, etc.

Hero is SB w/ 22. 5 limpers. I have been involved in 2 big pots and had to lay down biggish hands.

flop 10h 3h 2h.... I overbet the pot to 120... Villain raises to 300, I think he has a medium PP or a 10 with a heart... I decide he doesn't have the flush and push. ???? is this okay?
