Hello Boo,
I think you have the most wonderful attitude to what sounds like a real horror story. Like everything we encounter in life, some relationships help us learn so much about our own strength and ability to forgive. This one seems as though it provides the opportunity for so much learning.
You have already started reclaiming your own power and have begun taking the time and actions which honor who you are and your own self worth. It seems to me that just continuing along this path is the most helpful and loving thing you can do for yourself. Not being angry and accepting this very difficult situation will also help you heal and move on.
I so admire your courage in looking honestly at what has occurred and being caring about what happens to the children who are involved. You are right, this will not break you, it will only make you stronger and I am sure your positive outlook will bring you healing and peace.
Love and peace,
Marilyn
