I'm putting him JJ because of his awkward check. I'm guessing he was trying to slow play, hoping you'd hit the flop? I feel like he'd bet out AK or AQ.

The $55 bet looks like a weak attempt from you to take down the pot (1/3rd of the pot roughly?) So he may be putting you on a bluff, and be fed up with you trying to steal his pots. I like the call, even though it is a hard one to make.
