Hello Mircea05,
Welcome to the NL BSS Hand Evaluation Forum! Hopefully we will see more hands from you in the future, so we will be able to help you fix your leaks and as well help move up the limits. We will be waiting for the next hands and till that good luck on tables!
About the hand:
Yes, I'd rather raise the turn while his play really looks like a draw. Usually people tend to donk this small with some kind of draws rather with strong hands. And as played the river there is not much you can do, he likely managed to get the flush.
Best regards.
