When Mrs. Hammer came back from Rehab, she "caught" a Lying Addiction. Ran almost a year. Just weird. The kids and I made God Box for it. Called 100 Lies in 100 Days (sort of a joke of the 90 meetings in 90 days, they are supposed to do).
Seemed at about one year back it dropped down. Other AA folks have told me they that happen to them also for about the first year. Mrs. Hammer will still Lie about the Lying (yeah, really
). So we do not tend to press it.
Do you think your X is trying to stop his addiction(s)? Stopping tends to make some (or most) go at least a little crazy.
