Hey, I felt pretty dumb after everyone had accepted the divorce from my first (nice/long-time-sober) husband, I get married about a year later, and after a matter of MONTHS living with new husband I had to tell everyone I was leaving because new husband had gone back to drinking after almost dying from it.
Sure, they were dismayed, but mostly concerned about my well-being. The only real (though relatively trivial) burden was on my brother, who let me stay with him for a week till I got my new apartment. I had to take a short break from my child support payments (which I repaid, with interest, a short time later--first husband was also concerned about me and trusted me to make it right). It all worked out, and everyone was happy I didn't waste more agony on that situation.
