Tough position to be in especially with the children. I took the approach Besty suggested above and basically said I can't do it anymore. If you aren't honest about this, it is going to eat you alive. You will hate/loathe yourself for being intellectually dishonest. Take a long look at youself in the mirror and ask yourself if you are going to try and be brave and courageous and do the right thing or not?
I haven't been to a meeting or service in several months. Service went first, then fewer and fewer meetings.
