Seesaw
You have not sunk to a new low; you have not sunk at all. In fact, you are thriving! Although, I understand why you would feel that way.... I would have felt the same way as being rejected is not a delightful experience. And, not sure if you do feel this way, but I would have also felt discouraged and hurt because the lack of romantic love does not hurt until I am reminded that I want it; and having a crush on someone is a poking reminder in the heart.
Although, we both know that there might be several reasons behind his ‘no’ and it may have nothing to do with you.
I still think that it is amazing that you initiated friendship.
