She knows that you don't love her, you know that right?
In fact, almost everytime in history that someone, anyone, has said that they were lying, the funny thing is that people actually believe it these days, it's the most grand delusion of grandeur we have ever witnessed.
Not only do people, everyone, hardly like eachother at all, although there is the honeymoon phase, they most certainly care not for eachother's well being or most of the time even their own.
Her problem it sounds isn't only the schizophrenia, it's being like everyone else in almost everyway.
So what you need to actually do is do some thinking on our little situation down here.
We are just like you almost in everyway, thats our biggest problem.
