My husband of 21 years started having an affair in 2000. it lasted 3 1/2 years. I found out about it after 3 years. There was absolutly no hint or warning other than his distant behavor. Can I sue her even though we are still legally married and living together? She has never been married, is 54, no kids, self employed and lives on 30 acres. Also, how does this involve him legally? Many more ??? to come.
