Is this a new thing or did you know this about him before you were married?
I am quite liberally minded when it comes to recreational drugs and alcohol used responsibly. There is also a ‘more reasonable time’ in a person’s life to be doing such things and for many it’s a phase they go through in their early 20’s and then calm down and start looking after themselves better. But many people don’t calm down and develop long term problems with addiction. You don’t mention your age.
Money aside, his work aside, does the alcohol and drug use affect your relationship? Only you can decide if you’re not happy spending your home life with a man who’s not clear minded 7 nights a week.
I have seen relationships where handing the money across to run the house rapidly develops into a situation where he feels like he is buying his right to do what he wants. Like I say, I don’t know you or your husband but I would be concerned about drinking every night, no matter how small the quantity, and binging at the weekends “because.”
