“I can’t live without you!” Does that mean that the one who says it really really loves you?
It’s a romantic thing we say to each other, but if your prospective partner shows signs of really believing it, he or she is not reality-based, and you should run as fast as possible in another direction. Love means being a whole person who doesn’t need another person but can choose freely to love that person. Love may mean carrying on alone what you and a loved one have built together. The traditional marriage vow reminds us of this in the words until death do us part. It is not the happiest part of the marriage vow, but it reminds us to live and love and rejoice in being together in the here and now and that someday, sad as it may be, one partner will have to carry on without the other.
