What you give is what you get.

"If you don't want somebody to leave, then give them a reason to stay.

The problem with us, we don't want to get left behind but we are not giving them a reason to stay -- we are blind to our own mistakes but we are good at pointing our finger and put the blame on them; we are good at expecting something that we cannot even give, like love. What you give is what you get. If you keep on hurting the person and you're not making them feel that you're worth staying for, then expect the unexpected."
