I have a sneaking suspicion that you are behind here. I just don't see what he could have that you beat. I'd prob cc turn and try to get to a cheap showdown. But I'd be careful, as if his turn bet sizing looks like he's setting up for a river shove, which I wouldn't be calling, it may be better to get out sooner rather than later.

The only reason I'd say c/c rather than fold the flop is that there may well be some complete air in his range, and you may find he closes up now that his raise has been called.
