Greetings,Players! 6th Str. Dilemma..Hmmm

[SittingBull]

My heads-up opponent is about 75,serious looking,but unknown to me.
He is a loose 3rd and 4th Str. player.
On 5th,the Gentleman fires away with live rainbow T J K respectively.
I 2-bet with my completed flush.
On 6th,the Senior pairs his doorcard and I obtain another one of my suit.
The dealer announces: POSSIBLE FLUSH!
The Gentleman glances at my hand and fires away. Hmmm.

Assuming pot size is 6BB, what would U advise Sitting Bull to do in this spot??

Just wondering.
