my opinion? nobody who is SERIOUS about recovery would make a ten dollar bet with their minor child about it.
best to keep expectations down to around zero. i think i would offer some caution to DD as well.......yes it is ok to hope that her father really gets it THIS time, but the key here is you all have been here before, with lots of talk and promises. but try not to be too surprised or disappointed should his dry spell not last very long.
yes people do have moments of clarity and have a complete change of heart and mind in a single flash, often when faced with life threatening issues. as they say, there are no atheists in foxholes. and yes it would be wonderful if you didn't have to deal with addict crazy anymore. but i wouldn't be calling the attorney and modifying the parenting plan just yet.........
