My fiance wants to make our cat our best man.

The problem with that is, I've never really been interested in anyone else.
While everyone else in my class was chasing boys, I was uninterested, I just didn't see the point of dating with no feeling attached to it, and anyone who was interested in me were promptly turned down. (And I was called all sort of nasty names like the C and B words, along with stuck up for that reason)
My fiance and I started out as friends and we moved up from there.
I understand what you mean, though, if it were the other way around, and someone my age was engaged, I'd think "Are you sure you know what you're getting into?". You're not the first to tell me this, and I appreciate advice, I just don't like the idea of someone telling me I shouldn't do something without knowing the exact situation.

He's one of those guys I literally cannot picture myself with anyone else. It's hard to explain to someone who doesn't share the same feelings, especially as young as we are.

Like us, it wasn't a question of if we would get married, just when. He just fit, I couldn't see not talking to him every day, and within a few hours of seeing him I couldn't not see him being a part of my life. Dang, it is hard to explain... Having him there was natural, right, and couldn't be any other way once you see what could be. Good grief, sounds like romantic nonsense put that way. Natural is closest for me to describe it as, meant for each other.
