turn play for non-nut flush in unraised pot 2/4 6 max

[jaguar]

This is on prima so i couldnt get a proper hand history.

Me on the button with 350 all opponents has me covered. utg+1 and cutoff calls and i do the same with J [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/spade.gif[/img]. SB folds and BB checks.

Four to the flop of 3 [img]/images/graemlins/spade.gif[/img]6 [img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/diamond.gif[/img]. BB a tight agressive player bets out for 14 into the 18 pot and all fold to me. I usually play my flushdraws slow or fold when implied odds doesnt seem to be that good but this time i decide to reraise to 40 hoping to get a weak T to fold. Opponent calls and on turn i hit a lovely 8 [img]/images/graemlins/spade.gif[/img] for a flush.

Pot is now 98 and opponent checks to me. I bet 70 hoping to get a call from an A[img]/images/graemlins/spade.gif[/img]T [img]/images/graemlins/club.gif[/img] or similar hand. opponent now minraise to 140. I have about 200 left.

What do i do??

Is my line messing up a very simple hand?
