Break ups and how women and men deal

I never got the whole thing if break ups and how the different sex react to it. When we are in a log term relationship and things don't work out. Men are usually the ones who get back on the saddle right away, literally sometimes the same week of break up, while us women go to our local store get a huge tub of ice cream and snack and cry our eyes out. It stays that way for us for a while and the man has clearly moved the hell on. We are the ones texting and calling and pleading. But after a few months us women get out of our rut and things become better that's when men start to realize what has happened, what they are missing, they go to their local store and get their favorite ice and snacks, they do the text and calling and pleading. And at this point of them realizing what they clearly have lost us women have finally moved on. Why is it always like this?
