So, discarding for a second the fact that none of the relationships in the show make sense (even the non-romantic ones), there is still no reason for the episode to end as it did.
The whole premise revolves around Barney misleading Robin into thinking he's in it for the long run with Patrice, thus making her jealous and wanting him more etc. Robin falls for it (because the plot calls for it) and they inevitably both end up on top of that building where she finds the last page of the Playbook where Barney's entire plan/play is described.
Upon finishing reading she lifts her head and sees him standing opposite of her. She then goes on a rant about how this was not OK and even someone like him was supposed to know how manipulative and deceitful this play was, too much for her to now be able to ever trust him. Then he bends the knee and she says yes.
...What? Did you not just go on a tangent about how you would never be able to trust him? How do you see this working? How did you claiming to not be able to trust a person lead you to agreeing to marry him? There is no cause and effect connection between the too, it's retarded. There is no way realistically for them to end up together, but apparently the writers had a real hard on for them being a couple so they just wrote it in anyway.
The show is rife with social premises that have no basis in reality, like how Robin spends an insane amount of time with a group that includes not one but TWO OF HER EXES. Don was really on point when he made that observation, surprised he didn't haul ass sooner. And when characters actually try to make it out to be insane when Victoria leaves Ted for refusing to end his friendship with Robin, you know, his ex with whom he keeps daily contact and relapsed with and has the "if we're still single by the time we're 40" deal.
I like the show, I really do, part of the reason I watch it is because it's just a group of friends in scenarios that wouldn't happen in real life. But instances like this really remind how this show just doesn't care about integrity or consistency.
