Do you have a friend who constantly talks about her life, especially her boyfriend?

While it doesn't seem like you are jealous...I do think you may be tired of hearing about it. I had this problme with a friend too, except he was a guy who talked about his girlfriend ALL the time. You have to meet them in person and tell them something like this. "Hey Erica, I'm really not trying to be rude or mean but...I don't really need to know that Brian paints your toe nails while he sings you opera." Or something to that effect and if she still gets offended, tell her "Look, I love you and I love Brian, but I don't need to hear about him 24/7. I'm happy for the two of you, really!"
