How does you're SO/DH/BF (what have you) introduce you?
I just watched a documentary on relationships. They said if the other person refers to you by name only, then they do not have a personal connection to you. They are not showing ownership.
DH always says "this is my wife,-----" . A few times wr have met new couples and the man or woman just says the other persons name and I am left wondering if they are married, friends, engaged, if one of them is a gay beard. LOL
