Why do many guys go cold after break up or when girl rejects them and what is the best way to behave after such a thing for guys?

Suck it up and move on. Don't try to be just friends, that's just putting salt in the wound.

that is best way to deal with break up and rejects, keep the mind busy so you think less about that person. keep hate and jealousy under control that is the worse way to behave.
