Country singer Sara Evans, alleges in divorce papers that her husband committed adultery, was verbally and emotionally abusive, drank excessively and frequently watched pornography in their home. Evans, 35, filed for divorce Thursday from Craig Schelske of Salem and said through a spokesman that she was quitting ABC’s “Dancing With the Stars” to “to give her family full attention at this difficult time.”The couple married in 1993 and have three children ages 7, 3 and 2. In a statement issued Friday evening, Schelske, 43, denied the allegations.“I have made the decision to forgive Sara for the unfortunate campaign that she and her publicity advisers are currently waging,” he said. “… Sara has unfortunately become a dramatically different person over the last year and it is something we have struggled to deal with. Sadly, it appears we have failed.”
