$10NL, nut flush on a paired board

[muffins]

Hi all, would love thoughts on how I played this and what to do in this situation. I've been playing quite loose, raising any pocket pairs from any position and suited aces and suited connectors on the button/CO. Villain is 70/60 or something crazy over 50 hands.
