I can *feel* the pain. I've had several situations like yours in the past. Recently, my ex-mother-in-law came into town to stay with my ex-wife. After about a week at her house, she came knocking on my door. "She couldn't
stand one more minute over there." she told me. I reluctantly agreed to let her stay till the end of the week. I mean, what could five days possibly hurt? I had to be at work early in the morning and she decided to get drunk every night and raise hell. She made it two nights and I had to toss her out. She hasn't talked to me since. (Not that that's a problem

)
I just recently agreed to let my oldest son's mom stay with me the month of December. I can't wait to see the fireworks on this one.
