My H and I don't even have an LS, just an unofficial one, and he is already telling people we are divorced. My sister's STBX has been telling people he was divorced since he first left her 18 months ago. I think it is a way some people use to make themselves feel better about extra-marital relationships, b/c it distances them more from the marriage. Legally, an LS is still a marriage. If someone has a PA during that time, it is still considered adultery by the court system.
