River makes low two pair but completes flush

[KCrow]

Villain is 55/22/1.8

I didn't Cbet the flop because he's been playing back at me a lot with CR's and never seems to fold to my Cbets. I feel that I'm ahead on the turn (probably should have raised). Is this an easy call on the river?

If villain is that aggressive you should be tightening your opening range and let him play back at you with a stronger range.
