I want to know....
do you as a couple hang out, so socialize with others you work with?? We have, just not often
or people you DH/DW work with?? We have, just not often
What about the boss?? My boss, yes
Are you good friends with someone that works with you DH/DW or them for someone that works with you?? Nope
Are you comfortable with your DH/DW being friends with your co-workers?? Sure, why not.
is she/he ok with you being friends with her/his co-workers? No, why would they be
I have a couple of work friends that have become "regular" friends, I have no issues whatsoever with DH knowing and being friends with them. DW doesn't really hang out with her work friends, I have met one or two, and she doesn't have any issues with my knowing them.
