I think posting this HH without your river decision and the results of the hand would get way better advice.  

But being completely honest i think your assessment in you OP is spot on.  I'm betting this flop A TON of the time, rarely checking behind.  But as played OTT, folding river is a must especially with his sizing.

What was your thinking when checking back flop?  just curious

I think what DialingUP420 said is spot on.
