Being in love is so intoxicating, that special person so compelling, that lovers often drop some of the obligations and rules that dominated their lives before they met. When you're in love, you may forget that you don't usually allow yourself to splurge on perfume, or write poetry, or be wildly sexual, or say no to invitations you'd rather not accept. When your relationship is over, the bleak prospect of going back to the rules can drive you to the brink of despair, making you pine obsessively for your lost love to return and free you again. Eliminate the middleman. Free yourself.
You can start by making another list. This time, write down all the forbidden things you allowed yourself to do when you were madly in love with someone who was madly in love with you. Now give yourself permission to do all those things anyway.
What did your relationship give you permission to do?
