You're a family of strong and brave women. This is heartbreaking to read. Life just isn't fair and it's horrible at times.
I'm sorry you and Morgan are going through this. It sounds like you all have a rough journey ahead. As you said, he will do it again. I hope Morgan's plan of her and the kids being more ready next time works out. I don't think there is an answer in these situations. It's about survival and it sounds like she's in survival mode.
I wish I could do more to help. Sending my love and support for this journey. 🩵
