I think you are entirely too hard on yourself. Do you feel that you need a relationship to make you happy? Is it the marriage of your other friends that makes you feel as if there's something wrong with you? Well... that would just make you a part of the herd, wouldn't it. There is nothing written in stone that says you must meet and marry. Consider yourself a free-thinker who does what she wants when she wants. If you're waiting for "the right person"... then you haven't yet found yourself. You have a great site and I'm glad I stumbled across it. I humblely offer mine:
