Hero....?

This hand is just strange, and not well played from the start...i know. But does he RR me on flop cuz of my small c-bet? but oop why does he RR so small? What should i do with this, just throw it away? Or is he playing on my weakness here? Call and evaluate river or just fold cuz were both semideep and i have a marginal hand? Thx for advice for the whole line even if this might be more standard then i think it is.
