push on the river?

[Jeebus]

I'm playing in a .5/1 home game 7 handed with guys that i have played with for years. I have about $25. I have a strong read on villan who may have me covered by a dollar or two. His preflop call normally means something like suited connectors or little pp. He overplays these but will never reraise with them. He also never leads out the nuts and will push back with tpgk.
i am in mp with k9h villan is sb
ep1 calls $1
ep2 folds
i raise to $3 (not necessarily a great bet but i had seen the next two players ready to fold)
they fold and villan calls
bb and ep1 fold
post $8
flop comes Ah9cAd
villan bets two dollars
I raise to five dollars
villan calls
pot $18
turn Jh
villan checks, i worry he caught a jack but doubt it
i bet $10
villan thinks for awhile and calls. At this point i am confused as to what he could possibly hold and i think i give off a tell to this nature.
pot $38
river 6c
Villan checks, i check because I think he will call anything based on my reaction.
results in white:
<font color="white">hero has K99AA for two pair
villan has 1010AAj for higher two pair wins $38 </font>
Thinking about it, even though i only had about $10 left pushing probably could have bought me the pot since he seemed to be playing scared but overplaying a pp. Any opinions?
