"W has even stated as much, she lost her way and left her values and morales behind. She is very down about who she has become."

This is a great start. You can't let her wallow in that for too long, but it seems like a great start for showing you remorse and allowing trust to build. To me, having the person admit they have made an immoral choice is half the battle. It sounds like you're in a pretty good place.
