wow..this sounds like my W. she is moving out the weekend of the 18th to "find herself" too. i did a separation agreement with her. she still hasnt signed it. i dont know that she will. this is so hard. i feel your pain when it comes to telling the kids. that was so hard for me to do. keep trying. if it doesnt work, you will know you gave it everything you had. if it does, then you live happily ever after. good luck
