What's wrong with the way we love?

You know my mind began to wonder
so as i sat i thought to myself
everyone is either unhappy,with a broken heart,separated or divorced
is anyone in this world in a happy relationship
where both are in love and don't want anything else but what they've already got
please tell me,show me,teach me how this is possible
because all i see is that and even i was with the one but he doesn't love me back
and the other loves me but i don't feel the same for him
what`s going on these days, cupids not doing such a good job
