preflop - don't mind limping, can argue for raising (i probably limp more than i should). Can't see folding this hand in CO.
flop - not bad the way you played it
turn - hate the J, so many players limp KJ and the board now has 3 diamonds, I proceed with caution and call
river - call, so many times you'll see a weak K, pocket pair (that limped preflop) such as Q's or T's. most likely MP2 is either WA and hoped you would come over the top on the turn also or WB and wants you to believe he already has his hand or that the 5 helped him (i.e. A5 or such,that scenario only likely for a complete DONK)

all in all you played this similar to the way i would have played it.
