Some Friend

If you have a friend (married with LDR hubby) who's trying to get your hubby's time and attention away from you but disguises it as only friendly outings and all. But hubby tells everyone that he gotta ask your permission first. And if she tries to pm you and get friendly but tries to make you feel that she knows your hubby better than you (to think they only became friends a couple of years ago)... What would you do? Will you confront her?
