With your raise you bet $32.5 into a pot of $56.5 (48 plus the 8.5 button still has) and your hand should be good enough to do that. But, as said above, instead of checking the flop you should have bet the pot hoping to take it immediately.

I also don't like the pre-flop raise from early position with a, albeit double suited, low hand. However, this gave button the interesting opportunity to shut out the blinds with a hand he figures to be doing well heads up. That possibility is a further reason to bring it to a showdown with 3 pairs, 2 backdoor flush draws and a low draw.
