I don’t get this compulsion with baking. I very rarely bake , whether it’s cakes or bread . Mostly due to high fat and sugar content and I rarely eat them. Health and diet is so important as you get older .
I feel from your post that you need a hobby or an interest . Which I totally get . I retired in June last year and made the decision to try new things . I started wild swimming, although not in the winter ( I’m not that hardcore yet) . I volunteer in a charity shop and joined a litter picking group. I do yoga twice a week as well . So do things to please yourself not your husband. With your IBS in mind you could do a course on nutrition.
Good luck
I've got another 'keen'... Ouch!
