How to identify potentially harmful friendship
Yes, men and women can be friends, but it doesn't mean they always should.
If you have a friend who could be getting in the way of your relationship with a spouse or partner, ask yourself the following:
Would I be willing to give up the friendship to save my relationship?
Am I uncomfortable telling my partner about the time I spend with this other person?
Do I flirt without realizing it, or do I realize it and do it because it feels good?
Can I confront this person about having boundaries/clearing up mixed signals?
It's up to you how you proceed with friendships, but be cautious about perception on all sides!
