Right, love and hate spring from the mind.
They did tests on people, and love and obsession are actually synonymous with each other in cause. The way a person acts on it determines which is it. For me, love for my ex was more, I was concerned about her well being and thought of her before I did anything at all.
Hell I even left her because I thought she’d be happier because of how she was acting towards me. In retrospect we’re probably both better off. Sad thing is I still sometimes wonder if she’s doing OK, despite I found out her whole sob story when I tried to get back with her, was most likely a lie.
