No yelling from me, do whatever you want, it's totally up to you.
I will say , even if he is clean now, which I doubt,everything will not be right, and the chance of this working this out long term is slim...he is not who you want to believe he is.
Talk to him, email him, lift the RO, do whatever you really want to do, it's your life, your choices, but remember, your choices will effect your children for the rest of their lives. Be prepared to stare them in the face 10 years from now, and justify your decisions.
I wish you the best,
