i have a mantra i've been playing over and over in my head

he doesn't love you, he doesn't care
of this you must always be aware
stop your fantasies, step back and think
he cares less about you than his next drink
be strong and please don't bend
you know in your heart this has to end
he reminds you of another, take a look back
the ones you love never love you back

if i think it enough, i may start believing it...i hope it helps
