Why we need to cry because of a boy?

Today, my friend cried because her crush are dating with other girl.

The girl volunteers come to my friend's class and told her everthing.

And she cried       .      Cried          .       Cried      

Till whole class including her crush know she love him.

AWKWARD 

And I don't know what to do .._..
