To Every Girl: watch what you do to guys

I've seen him after you left
seen him broken and hurt
i've seen the pain
tried to heal the broken heart
i've seen the tears
i've dealt with the issues
you walked away
you destroyed him inside
and then you jumped straight to the next one
i wish you'd look back
i wish you'd see his face
the heart i cant mend
and the tears i cant stop
just cause you stopped loving him
didn't mean he stopped loving you
