So my steal fails here but I catch a decent flop then make trips...but I don't really like how I ended up playing post flop. what would you do? also, call or fold river as played?

The SB is tag - 23/12/aggro after 70 hands, and seemed to be recently playing back against me since I was stealing and cbetting him a lot. I am prob seen as a lag, but was playing a lot tighter lately - had folded everything the last 2-3 orbits trying to recover my image.

I have no post flop reads, since we haven't made it to the turn yet - he raised me on the flop once or twice and I folded, and he folded a lot to my cbets.

about $70 into a $220 pot if I call

I ended up using all 15 seconds and folded. his line made no sense to me...maybe trips/boat, AJh, busted draw, but wouldn't a tag bet or raise most of these hands on the flop? maybe not a 5 or a draw. I dunno...
