So I see this girl who's a friend of mine (we had babies 1 day apart) tagging this other girl in posts. Well the other girl has been talking to and sending naked pictures of herself to my husband on and off for a while now (over several years). Now I'm not saying it's all her fault, my husband let her continue to do this and think it was okay, but she's known he and I have been in a relationship for the past 5 years and doesn't have any respect for me as another woman or for my relationship. I'm afraid she'll start doing the same thing behind this girl's back. Do I warn her what kind of person she is so she doesn't strike up a friendship with someone who ultimately will probably betray her.
