Letting Go

Today i found out why my brother and his ex- girlfriend of almost 2 years broke up.  My brother did something to here that i didn't imagine him capable of. now, don't get me wrong, it was nothing to crazy bad. but if my boyfriend did it to me, i would never go back to him. It made me sad to hear that my own brother could treat this girl like that. We all loved his girlfriend! the even crazier thing is that she still loves him and would like to be with him someday again, maybe work through everything.. (she is clearly a bigger person than me) so my question, how do we let go of the ones we love?
