I am going through divorce and I try not to share with mutual friends of my husband and myself. Those I confide in are "my friends only." I don't want anyone to have to feel they have to choose sides and I don't want to wreck my husband's relationships with our mutual friends by sharing stuff that could bias people against him. There are two sides to every story and I think with mutual friends, it is actually best if they hear ZERO sides rather than two conflicting tales that test their allegiances.
