I really, really hope that they will end up together and that the writers know that Barbin/Robarney (ok, that's horrible ) has a giant fan-base (in spite of the fact that in this poll they're head-to-head)
I'm guessing that Barney proposes do Quinn and somehow later realises he belongs with Robin
However, if he proposes to RObin and things go smoothly all the way to the end now - I will be a very happy gal. This show has, what 1 or 2 seasons left, and I hope that the writers won't drag their relarionship out.
If they are meant to be together at the end of that show, great, get on with it already. If they are not, fine. But for the love of pizza, DON'T DRAG THIS OUT ANY LONGER!
