It's funny I kinda feel for Liz, it was kind of a douchie thing for David to do but when you take into account he was honest from the start and she was increasingly obsessive and all in out crazy I don't blame him for wanting to be a nice guy, a horny guy, but still when you deal with crazy and you know it's crazy who wouldn't be scared to end the good sex for fear of the fallout. I definitely want to know more about Liz!
