Congrats on your five days!!
It may or may not be progress. As you may have noticed, alcoholics sometimes say things to please others, but having HUGE mental reservations in the meantime. If those reservations are harbored, sooner or later they tend to win out over whatever acknowledgements of a problem were made. Not to be totally negative here, but that is the reality.
Whatever he does, do NOT let your concern with him, or his actions, jeopardize your own recovery. It is very fragile at the moment. Five days is awesome, but there is a lot of work for you to do.
Keep comin' back!
