Great advice here.
Life is better w/o an addict in it. He is saying things that are not recovery (take me or you lose your chance... which is pretty funneee if it were not so serious!). Tell him you will let this chance go by..
If you have a good life now, why hit the replay button and go back to something you know is bad?
With over 6 billion people on this earth I am sure you can find someone who doesn't need a bottle, pills or something to smike to make his life complete.
Tell him to move on... and tell him his first responsibility shoud be to his child anyway.
