Sb bets, I call, UTG calls, CO now pops it up out of nowhere, Button folds, SB 3-bets, I call, UTG folds, CO caps, SB and I call

The only hand that beats me is T9, it seems like they'd have to have a nut flush draw or nut low like A2T9. Pot is pretty decent at this point, can I fold this losing only to runner-runner? Also on the turn, is my call ok of the c/r ok because of people behind me and two flush draws being out there (likely someone drawing better than me)? I think it was. Does anyone check/call or even check/fold turn here "because you're only drawing to 1/2 the pot"? Seems weak-tight to me I guess.
