My wife and I have been married for 10 years and we were friends for 2 before we married. In my opinion it makes for a better relationship. We didn't do all that fake stuff you do while you are dating, because we already knew eachother. I didn't know however that from day one she was attracted to me, and I was the one that finally made the move. My advice is to just go for it and see waht happens. Don't look back later on and ponder what if.
