If you were in the mall with your SO/fiance, and ran into an old friend, how would you introduce him?
"This is (insert name)."
"This is (insert name), my fiance or boyfriend."
Is it important to you that others know who he is?
* I have a friend who says it's not important to let others know who he is, it's none of their business. This is true. However, I see it as respect. It's letting your SO know, what place they hold in your life, how important they are to you.
