I can only echo what Job, Matt & Mighty have said. I am so sorry to hear about your situation, your health challenges and what you and your kids are going through. As you said, life's ordeals teach us what is really important and right now, your H and his behavior does not matter.
What matters is YOU, your health and your children. Please take care. I hope you have a strong support system to help you go through this.
My thoughts and prayers are with you and your children. You are such a strong, strong woman and an example for me. Thanks for sharing your story and please come back to post often. You can find some comfort and support here as well.
