Playing a baby flush? NL 5/10

[Ole16]

I have about 1200 and villain has about 1000.
He just sat down an orbit ago and has only played one hand so no read.
Villain limps UTG and it´s folded to me in SB with 52 [img]/images/graemlins/club.gif[/img]
I complete and BB checks.

Flop: (pot:3)

Ok so I flopped a flush and actually have great redraws. It´s an unraised pot though and I like money.
I lead for pot - hoping A [img]/images/graemlins/club.gif[/img], toppair or something is out there -

Villain raises to 90.

My move?

Thanks in advance.
