How to do this is simple. Step back. Look at her from a distance. It's like standing near a fire. Get close you feel heat. Stand back feel the warmth, see the fire. Don't get burned.
She is dominant right now. Do your GAL with kids and for you especially. Stay at distance, emotionally. Google "Windsor Davies oh dear how sad never mind". 6 seconds of video. Legendary comedy but try to adopt this in your mind whilst being there to validate and always be kind. Tricky but it works.
Be a man. Give less of a sh!t about the drama. Guys don't in fairness.
Become the dominant man again - over you and your actions/feelings. I don't mean domineering over her. Just be a man. If that makes sense. As Sandi says, take your ball$ back. She doesn't know what to do with them in any event!
All the best.
