Part of sobriety is setting boundaries. Do you truly feel comfortable in being the person responsible for providing him with alcohol? I'm guessing you don't otherwise you probably wouldn't be here asking about it right?
It certainly could be antagonistic but you can set the tone for the conversation. State your intentions and let it be - you may need to back away from the conversation for a bit.
