One of the hardest things I did, and the best thing I have ever done, was quit worrying about what other people thought. Granted, it does still creep into my head but I am far more aware now to simply turn off that stinkin thinkin.
Families are strange in their ways. It's much easier to pass judgement on someone who is not related to you then it is to look inward at your own dysfunction. I know I have been judged and deemed a bad wife for moving out just when my husband sought recovery, but I don't care. My marriage is mine and my husband's business, end of story.
Try your best not to worry about it and focus on wrapping up the details of the move instead.
Take good care,
