Folks believe whatever they need to make them feel secure - Do Deny
Most recently I heard the expression "Nothing lasts forever". I respond too quickly because "I have learned this". The love my Mother and Father share, that lasts forever. My love for my family and theirs for me, that lasts forever. When we lose at love it is easier to believe it cannot last than to believe it can be eternal. If it cannot last, we have not failed. So now to those who subscribe to this belief I say, Don't worry. This feeling will not last forever.
