Falling in love has nothing to do with love. It is an unconscious compulsion, based on our unconscious mind reading her unconscious mind through her involuntary subliminal signals. It is a compulsion based on our unconscious pain and fear that we are not open to.
Be assured, that the compulsive attraction always turns into bringing our pain and fear to the surface after the infatuation phase has died out.
This is why experts warn us that the stronger the attraction is at first, the worse the relationship will turn out to be.
You only see here as sweet, kind, caring and compassion because you have not yet done something that pushes her buttons, her own inner issues. Your are not yet close enough to her to see her clearly. And you do not see that she is imperfect .. EVERYONE is imperfect.
Your belief that she is so wonderful is ONLY your fantasy about her. And the stronger the fantasy, the more painful the disillusionment will be when you discover that she is only human.
I supposed you will have to be a slave to your unconsciously-driven compulsion, and learn through pain. You sound too stuck in your fantasy to recover a grip on reality. Don't worry .. we all have to bash our head against the wall of Reality at some point in our life.
Just, please, when it ends badly, PLEASE go talk it out with a therapist so you can resolve your emotions ...otherwise, you will go through a lifetime of one obsession after another, becoming more and more bitter and therefore less and less able TO love at all.
