.25/.5 NL UB 5 handed table

Me UTG (stack 55) KK - raise to 1.75. My image is maybe a little loose, been playing lots of pots and won a couple small ones in the last orbit, without showing down.

Button calls (stack 70) - loose player, would call flop/turn bets then get out on river

BB calls - (stack 27 or so) odd player, didn't play many hands, but won a nice pot calling down a busted draw with J3 with 810QJ on the board.

Flop is QJ9 two hearts. BB bets 5, PS. I'm worried about sets or two pair, I call thinking button will fold wanting to see what BB does on turn if no draw gets there. Button also calls. Turn is another 9, not a heart. BB goes AI with his remaining 20... I fold.

Button calls and loses to BB's AJ as another 9 comes on river. I assume button was on the draw, too stunned to pull the HH to see which one.

Re raise on the flop for info? I was tempted but if re raised I felt I would have to give it up. On the turn is it AI or fold?

Haven't ring in a while, when I last played it seriously no doubt my biggest leak was not being able to give up big pairs after the flop, so I'm focused on that, but did I over think this?
