River decision with flush

[zaephyr]

I know pf call is bad, but i wasnt active latly so i gave it a shot.
Button was quite aggro so i was going for bet/3-bet on flop (he reraise donks a lot of times), and well BB ruined it.
I should probably make 18$ bet on turn, cuz he either calls or folds anyway.
River: standard value bet, then villian thinks for 15-20sec and pushes. I didnt have any strong read on him, but he didnt do anything stupid yet. So what do i beat
