After 30 days it's easy to mistake "no longer perpetually shooting myself in the foot" for sobriety. AA recommends that people not make major changes or get involved in a new relationship for the first year. The reason for this is that it takes up to 18 months for the brain to recover from the damage drinking has caused, and romatic relationships are a distraction from the hard work it takes to get and stay sober. As a practical matter, many do re-engage in romantic relationships in early sobriety, not always with horrible outcomes, but the odds are against success. My advice would be to keep separate living arrangements for the first year, and be very clear that he is in early sobriety - he is far from sober. If he values his sobriety he will make that his priority for the next few months.

As for marriage - that's in the category of delusional thinking at this stage of the game.
