Obsession or true love?
The difference is merely about projection. True love is where you see a person for who they are and you still love them. Loving someone for who they truly are, also involves understanding what your lacks are, ideals, childhood wounds, so you DO NOT project, but rather; you fulfil/heal these on your own in a healthy way. I wrote about the causes of obsession in my first book: How to make someone obsessed with you.
Obsession on the other hand is the complete opposite.
Obsession is selfish, and all about projection. Additionally, it’s about hope and despair. You see something about the person you particularly like: perhaps they’re generous and you think they’ll save you from your horrible financial situation, they remind you of your absent father but they show you kindness. With that in mind, it gives your mind a reason to project onto the person. What adds to your obsession will be when they show you that maybe they aren’t the person you’ve projected onto them.. then you become obsessed with them,,, like I said “Hope and despair.”:
