ITHFM ~ My advice would be to move back in and set up shop in the spare bedroom. Be nice, be respectful, don't cross her boundaries. Remember that you are separated but also know that it is far easier to DB from under the same roof. Further - and you'd REALLY have to GET THIS PART: You can't say a word - NOT ONE WORD - about what she does, unless it affects your son negatively. Otherwise, you have to zip it, bite your tongue and SMILE even if you feel like choking her. And you will. Oh, yes, you probably will feel like choking her at times.
