Do you believe it’s ok to have a “work husband” and or “work wife”?

Would you be okay with your significant other having a “work husband/wife?”

My actual husband has what I would consider a “work wife”. They are really good friends, and usually get lunch together.

I just started a new job and I’ve kinda imprinted on one of the guys in my team and I have the feeling he will become my “work husband” because we have a lot in common and he helps me out a lot.

(What I mean by depends on couples relationship is whether or not the work couple have set boundaries and are respecting their ACTUAL relationships. Or if they are flirting, being sexual towards one another etc)
