I have a group of wonderful friends I adore. Most of us have known each other for over a decade and are extremely close. One girl in the group is a nightmare. She makes snipey, rude comments, both about me and to me. She's judgemental, negative, and her favorite word is "actually" as she injects herself into a conversation to correct someone. Basically, she's the mean girl I promised myself I was done dealing with after high school. And several members of the group adore her.

I walk a fine line. I invite her to group things I plan (and she does the same), because I don't want her to feel left out. I try to avoid her or keep to surface conversations. I try to stand up for myself when she crosses the line, but usually I end up snapping at her and feel guilty for not being more patient. She's not close with many people, and I tolerate her because I love the people who care about her. If it ever gets bad enough I can't deal I'll have to do the time split thing you are doing, but I really hope it never comes to that.
