Showtime is in final negotiations with Marti Noxon for a half-hour comedy series called Guide to Divorce. Noxon, best loved for her work on Buffy, would write and executive produce the series about four middle-aged women dealing with both the perks and the drawbacks of the ends of their respective marriages, Deadline reports. Weeds is almost over, The Big C is drawing to a close —  yeah, we’re due for a new Showtime comedy about Ladies and Changes.
