No one can make you happy. Nor is it up to you to make someone else gleeful. Couples, often, confuse making their other halves laugh with being the cause of their happiness.
Deep-seated contentment can only come from within. Finding that enchantment needs to be a personal, singular endeavour. Each one of us must look inside for real fulfillment. And as a couple, by all means, take the partner along, but do not burden yourself with a sense of responsibility for another’s bliss.
Rejoice in your exalted jubilation, it can be extremely infectious. Spread the good cheer on, knowing you are ‘sharing’ not causing others to join in the fun. Everyone will benefit.
