The reason Hubby and I got engaged when we did was because I complained that when he called me his girlfriend I felt like I was only a temporary part of his life. So he proposed and said, "There, now you can call me your fiance."
I call Guy my boyfriend when I'm talking to people who know the situation, but I don't really like calling him that. We just haven't been able to come up with another term. As stated in my signature, he prefers to avoid labels, but I need a term for him because that's how I am. When I'm talking to people I'm not "out" to, I just call him my friend.
And he and hubby call each other "Bro-hub."
