Comments on my river decision

[Kyle]

I am new to NL from limit. Villain in this hand has TAGish stats but IMO doesnt really play that well. I have been playing aggressive and havent had to show down many hands lately. He probably views me as somewhat laggy but decent.

I have about 125 and villian has 150.

100 6 max

villain limps UTG, I raise to 4.50 from Hijack with AKo, retarded cutoff calls as does the sb and limper

flop comes K 4 3 two diamonds.

Checked to me, I bet 12 into a 19 dollar pot. Only villian calls.

Turn comes 6 clubs putting two clubs on the board.

Villain checks i bet 20 into 43 pot. Villian calls.

River comes a 5 missing both flushes villian pushes for 110. I have 90 left what is my plan?
