Confused with TT

[ZZZ]

Party 5/10 6-max

I have T [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/diamond.gif[/img] in SB.

UTG limps, TAG raises, 1 cold call, 1 fold, I 3 bet, BB calls, all call. Everyone but the TAG is pretty loose passive.

5 to the flop.

Flop: A [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]
I bet and get 2 callers, the TAG and one other folded. I was going to fold to a raise (or peel and check fold the turn).

Turn: 5 [img]/images/graemlins/heart.gif[/img]
I bet, both call. I was going to fold to a raise.

River: 2 [img]/images/graemlins/club.gif[/img]
I check planning on calling one bet, even if I have to overcall.

Did I botch this one? Should I have given up somewhere? Bet the river?

What's going on preflop? I'm pretty sure I win more than my fair share, so there's value in my 3-bet, but is this going to be easier to play if I just call?
