Here is the thing my girlfriend so can't love me, but has feelings. Keeps me around. Is that mean and cruel?

Well it's interesting; as interesting as why you would be staying around under those conditions.

It may be but if you are thinking it is, why are you staying? She can't make you stay. The choice is yours

You must have a pretty low opinion of yourself to put up with that. Why? Why not just leave and find someone that will care about you?

I would have been long gone, so how come you keep hanging around?
