All love shifts and changes. I don't know if you can be wholeheartedly in love all the time.
Love does not begin and end the way we seem to think it does. Love is a battle, love is a war love is a growing up.
Affection is responsible for nine-tenths of whatever solid and durable happiness there is in our lives.
I have found the paradox, that if you love until it hurts, there can be no more hurt, only more love.
