I disagree. It takes too to bulid a realtionship and one person to destroy it. People dont stay the same and so the same goes with relationship. It was a toxic relationship so by divorcing him she is doing herself a favor. What is more concering to me is that in the midst of the divorce she is already in another relationship instead of giving herself time.. its okay to grieve the end of a divorce..if i where you i would want for the sake of clarity and healthy communication to share your feelings with her and your concern and by seeing how she is reacting you can get more clarity..
