Is this infatuation or something else?

It's like I could have written this story...minus the beach and party thing. I do think it's infatuation though to be honest with you. A very strong one at that. And trust me, I know exactly how you feel. EXACTLY. But I really think you should've just talked to him and gotten his name at least. I mean, you knew you were leaving. But anyway, what's done is done. All I can tell you is that it will eventually go away. Maybe not completely but it will fade for sure. I know it did for me, but if I ever see him again I think I might pas out.
