I live alone now & can't remember how much of what I bought when I didn't. 🤷🏻♀️
I wash my bed linen once a week in winter, twice (or more) in summer. I like a fresh bed especially when it's hot! (Yes, I do air it, but washing two sheets & some pillow cases isn't a hardship (all white so get washed with white t shirts etc). The duvet generally lives folded up on a chair most of the spring/summer (it's there already. I just have a sheet & a light blanket on the bed.
Towels get hung up after a shower and reused. I'm happy to reuse my own towel a few days, then they (towel for hair, towel for body) get washed with the bathroom hand towels (several as they get replaced daily).
T towels & dishcloths get replaced frequently through the day and go in a caddy with laundry cleanse (detol the non sensitive one smells lovely) and washed when the caddy is full. On their own, not with clothes or bath towels).
showers once or twice a day, sometimes more if it's very hot or I'm getting ready to go out again. Just depends what's going on.
clothes - the usual knickers, bra, socks, t shirt are put in the wash each day, but jeans go 2/3days depending on what I've been doing. Cardigans/jumpers several wears - often quite a few wears as I'm a hot person who only has them on for short bursts of time.
you really don't need to be washing your cashmere every 2 wears.
I use olive oil bar soap as it suits my skin. It lasts ages!
I wash my long hair most days & shampoo & conditioner both last ages and I'm not careful about how much I use. (must try harder).
toilet roll - mileage varies.
toothpaste.. ages.
there does seem to be a few things you could change if you were open to it. I see you've said about cutting down on washing, that's a start.
many of us do what our parents did 'as the norm' but I think your parents were a bit excessive & overly concerned about things
what would you like to get out of this thread now??
what was your husband saying that you thought was wrong? Have you changed you mind at all?
