I tend to agree with puppy on the weighted words. You are hanging on to hope and why not if you want to drag this detaching on.
She is leaving, there is definitly another man. Let her go . Help her pack. she feeds you leftovers, why keep subjecting yourself to this abuse. Your esteem is taking a kicking , you need to give you some seriou thought.
Look from being over on the other side , i can tell you it is not greener. Pickings are slim and problems immense. This R she is in wont last. Let her then turn to you and see if your still there.
Why is friendship a precondition. Why would you want to be friends with anyone that turns your world into an ugly upside down, hurts your children, puts a strain on finances and is kicking you at every oppotunity. You can be civil and courteous but FRIENDS!!!!!!!!!. Let her earn that back down the track.
