limbo, dont think of it as a debt. You have tried to do something for the benefit of each person and it didnt worked as planned. It failed. Dont let that make you so miserable that you would give up HOPE. Hang in there, the pasture will eventually gets green again. I agree you dont deserved to be treated that way. That's exactly what my W says to me and now I can give her the very last dime I have.
You know what I have been thinking all through this time - we all have children and one day our S or D will get married. Do we really want to see them go through these same events we are experiencing. I think NOT!!!
See the W, Listen to the W, but dont Speak back to the W. Bridle your tongue...
