I'm in my mid 40s and dating this lady of a similar vintage. I am trying to find a good word to describe our relationship, but "girlfriend" and "boyfriend" seems inappropriate for us. It reminds me of those forty year old guys who say "I'm gittin' down wi ma hommies." It communicates, but it seems out of place.
Perhaps it is the "girl" and "boy" part that bothers me.
Any suggestions for something more appropriate?
