Jane was dating John then she dated Jack. Jack doesn't pay enough attention to her, because Jack actually has a life. Jane gets that. Jane doesn't want to be needy, but Jane needs a lot more time...and Jack doesn't always get her, or understand everything, but he tries really hard, and is really nice. John always went kind of psycho. Jane figured out that if someone is utterly devoted to you all the time, giving up their life for you, that's kind of insane. So maybe Jane is insane. But Jane does realize something: She is going to die alone. :)
