River play on flopped flush

[RolldUp]

Villan is 30/20/4, plays extremely aggressive postflop but not terrible, and likes to steal alot from the button. Should I check call the river or is my line fine?

Between the turn cap and the paired river card I prefer check/call.

Must lead the river. Sucks that you got raised.
