Being the Other Woman/Other Man

This is for anyone who has lost their lover to death and you were the other woman/other man in their life. We have to grieve in silence. I can't find any support groups and feel like I'm the only one going through this situation

My married lover

For 6 years I secretly shared a wonderful love with a man who was a beautiful soul. His other life found out about me days before he passed. His family has asked that I not attend the service. I called the funeral home to see if they would arrange some sort of private viewing, but was informed that he'd already been cremated. This grief is overwhelming.
