Hi Razor, congrats on day 5! Your post shows a lot of thoughtful awareness of your situation.
I think you're wise to talk it over with him and see how he responds ... and wise to be protective of your recovery in the early days. Eventually it gets much easier to be around alcohol, but I wouldn't have wanted it in my face at the beginning. Asking for there not to be alcohol in the house seems reasonable - you're not telling him what to do with his own drinking, just creating a safe place for yourself to get started on recovery.
