I have always had a good relationship with my SD 15 but now she seems cold and different. I'm not sure if its me just more irritated with her of if her BM has made her choose which side she is on. When SD was little BM said things like "oh, you like SM better than you like me" BM has always felt threatened by me (not because I try to compete) I just have always been caring and concerned for SD and love her very much. Any experiences with teenage SD with pain in the ass BM and how things ended up in the long run?
