You go broke here every time pretty much.

Bet more on the flop (eg you bet $0.40 into a $0.95 pot giving him over 3:1 to stay in with his bottom pair and hope to get lucky)

Again, had the same problem occured on the turn where he was getting about 3:1 to imrpove (though here the odds probably don't really justify staying in unless he was looking at implied odds which I dobt at this level)

The river push byhim though screams that either he has us beat or he's bluffing. With top 2 I'd find it hard to get away from this here as well (just ask my BR ) and by that stage it comes down to how over to you think he's bluffing vs having the set/flush since you're getting about 3:1 on the push.
