It seems like only yesterday you were posting about squirrels' nuts, or squirrels' bowels, or bowls...whatever.
Nervous is normal. Remember that love isn't only a feeling, it is a choice. Marriage is about choosing to put someone else first for the rest of your life. And I'm sure she'll be good at that, so stop being so nervous.
Seriously though, I'm sure you'll both be happy and continue to be awesome together. And I should know what I'm talking about. After all, I'm a stranger on the internet...Name's Tony, by the way, in case you didn't know, haha.
