Am I married to my pocket pairs?

Sorry for all the posts - I've been on a huge downswing for the past week and a half so trying to plug some holes!

Flop: (11 SB) A[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(6 players)</font>

I was folding the turn if it was 2 back to me but when the cutoff bet I thought it was a good opportunity to thin the field. Should I just bet out here? Check/fold?
