I have been married to my DH for 20 years and we have been together for 22 years. My SDs have been in my life for all that time and over the years we have weathered very mean problems and very many storms. Their BM was a bit of a fruitcake and many times we had to "rescue" them from various incidents; there always seemed to be some "other man" in their lives... the BM was the one who ended the marriage by having an affair (one of many) and I met and started dating their father after they had been divorced for almost two years.
