Are you sure you are falling in love, or are you lonely? Sometimes, people who fall in love easily and quickly are trying to fill an emptiness within themselves from being lonely for too long. And that is why the letting go is difficult, because you want that hole to be filled at all times. I can be completely wrong about this, but I'm throwing that out there anyway. You might need to evaluate your feelings a little bit more to get a better understanding of why you feel the way you do, or why you think you feel the way you do.
