Would you be ok with this?

Let me clarify:

This is not a friend we share, though I have met her before.

I’ve always questioned her motives with him because she has asked to meet up with him alone before.

He verbatim text her “I’m sorry I’m always calling you about my marriage.”

I think whenever we get in big fights he calls her to complain/validate his feelings/side of things.

Oh...and if I did the same thing, ie talk to another guy about our problems even if it was just for advice and totally plutonic, it would be WW3.
