Many people who are divorced go on to meet and marry wonderful poeple and have amazing marriages the second (or even third) time around. Marriage requires continued effort, passion, loyalty and mutual satisfaction on numerous levels...but most of all it requires commitment. If the two people are not committed to making the marriage work and if they are not committed wholly to each other, it will not likey survive. My parents had the most awe-inspiring marriage and I know that great love is possible. Be hopeful and optimistic...I have a happy and full life that I know would be even better with a great man next to me. In the meantime, I strive to become the best version of myself that I can be, and to be the kind of person I would want to marry.
