I'm just not sure what to do here, it seems really hard to get value from him with what i did. Should i use alternate raise sizing on the flop, or maybe lead?

I just bet here, cause any overpair etc cause put you on tons of combo draws (56,67,68,89,79,66) that might c/r this flop and bet this turn that they are still ahead of.
