True love is proven through the actions of your true love!! Not through the act of saying it!
It is impossible to fall out of love. Love is such a powerful emotion, that once it envelops you it does not depart. True love is eternal. If you think that you were once in love, but fell out of it, then it wasn't love you were in. There are no 'exit' signs in love, there is only an 'on' ramp.
