See if you can develop an interest that both you and your husband share.
Maybe you can do this together 3 days/week and the rest of the time you can quilt. I would hate to see the marriage fail just because he is jealous of your quilting, but you can imagine that if he were in the garage all the time building or fixing cars and if on the weekends he was off with his buddies looking for parts, you might be less than supportive of his hobby.
Also, since it is terrible for his health to just watch TV on the sofa, and since
quilting is also sedentary, maybe your time together could be more active -
bicycling in 3 seasons,& cross-country skiing in winter....
My husband loves genealogy and spends his time on the computer searching
for family tree development so I can quilt without ignoring him. But we are
careful to spend large blocks of time together - usually walking in beautiful spots that I find on the web. However, we are both retired - you look MUCH
younger so I don't know if this would work for you...
