10/20 Limit HE, 10 seat Hand - could you have gotten away from it?

Would it be wrong to just call the raise on the river instead of 3betting it? Almost everyone who raises on the river has a hand which he think is at least 98% sure to win the showdown. I hate having to fold two-pair on the river. I want to at least see what he has so next time I can figure out what he's doing. If you make it 3bet and he caps I don't see any hand you can beat here unless he has a QT too.
