Above all else you've got to do what is right for you and your kids P. Your W has a long road to recovery ahead and it could be years before she is someone you could trust and love again. In the meantime breaking it off with her may be necessary to help you heal. Good luck and keep us posted.
Thanks "AS", you are absolutely right. It will take this for me to heal and move on. She would never leave and she would never file. She could honestly live like this for a long time before she would do anything.
