As Sonni said, this makes one want to cry - for what you have lost and the way you lost it. But also for the almost physically abusive way your husband forced you and your mother to empty the house. You are probably right that his anger controls him, but can't these people at least treat us as humans?
Your mother must be quite a worker. I hesitate to ask, but weren't your sons or DILs available to help? I ask that knowing that however wonderful our adult children can be there are times they miss where we just plain need their help.
How I wish there were some way to draw the WAS back from the evil netherlands they fall into - and I do think they lose their consciences when they leave. I'll always wonder if they were just play-acting at being better people for most of their married lives (that's for those who did act better.)
