Keep doing what you're doing. Protect yourself, but let your wife do all the work as far as the legal aspect.
Good for you with not picking up the phone. If it was serious she would have left a message. If she was calling to use you as her emotional punching bag, it's fine to avoid it. It sounds like she has a lot of issues that she must work out for herself. Blaming you will not help her do this. It just gives her an excuse not to look within.
It sounds as though you're doing the mirror work on yourself. Keep going, you won't regret it.
Must be you're impressing the in-laws with your changes. Way to go!
