why dont barney and robin get married imean there perfect together

at this point in their life, they aren't looking for something that committed. I do believe, however, that it will eventually be revealed that Barney and Robin are married (or at least together) in 2030. :)

You're right though, they ARE perfect for each other. ♥ ♥ ♥

Well, they almost did, but they weren't really thinking at that point. I think they'll get married eventually, but for now, neither one really wants to be tied down.

The ratings will drop. D:

They might I mean you will never know because Future Ted still refers to them as Uncle Barney and Aunt Robin...

But sometimes I think it is like in real life, where even though 2 people are so perfect for each other, they might not end up together.

They are endgame!<33

Maybe did and ted dose'nt know about it.Have you notice in every flashback when ted is all ready married none of them included barney or robin.They might of and gone spepret ways.
