I am in the process of a bitter divorce. My son and his fiancé are planning a large wedding in six months. My children are unaware of the details of our separation, including my ex's physical, and emotional abuse; his use of prostitutes, and his many affairs. His extended family do not know what happened, and believe what he tells them. I would never want to spoil this day for them, but I wish I didn't have to go. How do I hold myself up with dignity?
