Why Robin did that to Barney, when they both agreed to be together?

well i'm gonnoa give u an answer of a true HIMYM Fan who Liebe all the characters so...

because barney is the risk,barney is the real deal if does losses him this time there's no going backhe should lose him forever and maybe even all the others,becuase if Du lose the real thing then Du would have to settle for Weiter best thing and robin just did that she took the Weiter best thing(kevin) if she losses him she will be sad but she wouldn't herz broken

i hope that helped but yes i agree with but she was just scared and i too was really mad at her but i still Liebe robin and understand y she didn't take the risk it's too much of a big risk to take

Because she's a fucked up bitch. I have always hated her. Yeah like Du sagte they BOTH agreed to break up with their significant others, but she didn't when Barney had to! The epiode had be in tears, especially when Barney was picking up Rosen off her bed. How could she do that to Barney? And now they're (possibly) having a baby? (If you've watched the Rebound Girl) I have never been a Barney/Robin supporter, but I am a BARNEY supporter. AND I HATE ROBIN FOR ENTERNITY!!!!
