Thank you to everyone. I agree - I need to talk to this about it. And if he using again, he is out of here until he gets sober or perhaps forever. That was a bottom line we discussed when he was in rehab and I think I can stick to it.
I was also curious about the "trail" of money he left. Makes me wonder if there's other missing money he was more careful with too. (Withdraws from the bank and took cash with him.) Even if it's not the drugs and is "only" alcohol, this is not okay with me because it's a slippery slope back to drugs and we agreed on a sobriety of abstinence. And even if he didn't use either, I am still not ok with him spending $140 at a STRIP CLUB when we are struggling financially.
The work outing idea isn't possible in this scenario with the company he works with. And, anyway, this particular "club" was where he used to go and use when he was active in his addiction.
Thank you again...
