Hang in there Tony.

"don't shelter her from her consequences" and two "protect and be there for your children"....this along with taking care of you and the children emotionally, physically and spiritually are all that you really have any control over for now. When I finally figured this one out I started to move forward. Let her go. She is determined to self destruct and you nor anyone else is going to stop her. So, let her. At that time she will have an opportunity to come face to face with the Almight or she can ask someone for a bigger shovel and keep digging. You can only pray for her. You may or may not want her back then but still do pray that she makes the right decision at that point (for her soul, the children, etc).

You WILL get through this one day at a time.
