it sounds as if he is dragging you into his own personal fight....or trying.
it's not your job to spoon feed him praise for staying sober and "not lying"....what is he a 10 year old finally learning potty training?
you say that you do not want to leave your children alone with him? do you not trust him for what reasons?
maybe he just needs to GROW UP and accept responsibility????/ or go back to getting a pat on the head from mama.
i'm sorry it's just that i never heard anyone expect to be praised for NOT lying.
