The fact that he wants those extra 45 days with her is kind of telling. Either he's just saying he wants all the time he can get with her because he loves her and has been waiting for her, or she was taken from him too soon and he wants more time with his wife now. And the line about loving her until the end of his days, well, that's part of traditional wedding vows, but it also sounds like a promise to the woman he loved and lost. Like we said, this speech can be taken a couple different ways, but we decided to take it in the most depressing context.

Some conspiracy theorist think that last line can mean that Ted is the one who is dead, but that's a theory to deconstruct another day.

Exhibit C: Where is she? We have seen every episode of HIMYM, and it's possible that we're wrong and missed something, but we don't believe the mother has ever been referred to in present tense in the flashfoward when Ted is talking to the kids. Not even a simple: "I better hurry this story up because your mother will be home soon." Sure, the show is called How I Met Your Mother, so the focus is always on the flashbacks and Ted's life before meeting her. But still, where is she in the present day that she never interrupts the story or is never referred to as in the next room or something?
