I'm a little late, but I will add my $0.02
First and foremost, do not post results in the OP. The results aren't important, and the feedback you get may be biased.
So preflop is fine. Flop is where things get tricky... We can float here, but I think raising is a better play. We have 2nd pair, and our opponent is donking into us. I don't like flatting here at all. Donk bets are usually weak hands, draws, and people trying to set their price to continue, and to find out "where they are". Your flat call looks weak, because it is weak. So, if you are going to continue, I think raising is better. If the dude just moves in, we can fold easily.
On the turn, before reading results, I was thinking V may have AJ. it is Def possible. I think raising the turn is kind of asking for trouble, and when he RR you, man, I don't like your hand too much after that.
You ran into the absolute best case scenario here. I think you overplayed the hand a bit... but it's not horrific or anything.
That's my thoughts anyway.
