Is This Love?

In the words of Robert Palmer " You can't you can't sleep there's no doubt in your in deep might as well face your addicted to love". My question for you is "when is it Love and when is it considered obsession? Years have come and gone but yet I can still replay every interaction we had. I still think of you daily and lately can't sleep because all I am doing is thinking of you. So twin flame? Or have just plain crazy? Did you feel the same? Or did you just catch on and was only flattered by it all? I can tell you I have never ever felt this way in my life. I researched for hours trying to figure out what was this magical thing between us. Not understanding then read what it feels like when you meet your twinflame. It was everything I felt but yet I felt crazy then now years later I am still questioning my sanity. I just need to hear it from you, from your mouth to my ears what you felt. That won't happen so how do I resolve this? How do I move on? For those who say " It is better to have loved than to never loved at all" obviously never suffered the pain I felt from loving you. So how do you get on and live life when the only person you want to do this with is not available and how do you know if they felt the same or not at all
