I'm too dumb to know if this is terrible

I'm blowing off some steam by semi-shortstacking a 2/4 NL game. Effective stacks ~$220
I raise to $12 from UTG (6-max) the with A [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img]. I doubt that I have much of an image yet. I get called by the CO, Button, and BB. The Button is loose and awful and tilting and will get it in with insufficient odds with like any decent draw. He's also squeezed preflop a couple times. No solid read on the other opponents but they haven't done anything out of line.
Flop T [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/diamond.gif[/img]. BB bets $12 into the ~$50 pot, I call, CO calls, Button makes it $50 to go, BB folds ... I push, of course. OK?
