I raised pre- got called, villain donks small into me and I make it a bit more because I think he can be doing this with any type of draw, combo draw, pair + draw type stuff I still think Im ahead most of the time on the flop

On the turn he bets out half pot and I find this interesting, still unsure because the board is so wet he can have alot of stuff here I decide to just call . On the river he bets half pot on a 5 which doesnt complete any of the draws. So I think he might have picked up a Q sometimes, a set, or a 5? what are your thoughts on the hand. Im getting 3:1 on a call am I good here 1/4 of the time, the reason I re-raised small was because I wanted to keep much of his weaker ranges in the pot still and fold if he showed aggression on an ugly card but on the turn when he donk bet again I got a bit confused on what he can have here I felt like many players would play theyre nutted combo draws this way .
