For Christmas we were with my husbands family, his sister was there which we don't see often. The next day I seen on Facebook that she had became friends with my husbands ex. Isn't it odd that they were together the night before and now she's friends on Facebook? I asked his sister what was up with that and she said they never talked about his ex that she just wanted to be nosey. She is a pretty girl but has very revealing pictures on there, we have had problems in the past because of her. My husband is not friends with her on fb but he can see her profile n she can see his since they have friends in common. Should I be upset?
