They don’t deserve you.
"Hi. I’m Ted Mosby. In exactly forty-five days from now, you and I are gonna meet. And we’re gonna fall in love. And we’re gonna get married, and… we’re gonna have two kids. And we’re gonna love them and each other so much. All of that is forty-five days away. But I’m here now, I guess, because I want those extra forty-five days. With you, I want each one of them. […] Because… I love you. I’m always gonna love you. ‘Til the end of my days, and beyond.”
Ultimately, Barney and Robin are in love. I wouldn’t worry about them being tested. It’s their wedding weekend. They’ve passed the test. – Carter Bays
