NL25 FR: Do I have to call this river?

[jmillerdls]

Seems like he's blocking with a flush draw, and then just bluffing the river...but I get burned by calling river bets a lot, so I'm getting a bit gunshy. What do you guys think?

Also, how is the hand played up until there? Just call the turn maybe? Looking back, I'm guessing $4-5 on the flop would have been more appropriate.
