Very well done, Ella. I've been off line for a few days so missed your post.
You have shown such determination and will power. Retirement is another phase of our lives, and something to adjust to. Not everyone finds it easy. You are wise to be seeking other interests, and I think Bradford lass has posted some very sensible thoughts on what you could say to your husband, as it sounds as if he is probably finding retirement difficult too, and sees it as something you do together as if stuck by glue. This, of course, as you recognise, is not healthy, and you both need time to yourselves, with different interests as well as Ines you can pursue together, as this in itself will mean you both have interesting things to share with each other when you are both in.
The U3A seems a good idea, plus there might be a women's Institute (or similar) near by, a knit and natter group, or something advertised in the library, such as a local walking group or the Ramblers Association. Perhaps there are some RSPB sites nearby, or National Trust/English heritage properties and gardens to visit. These places are also often looking for volunteers. There are also some very interesting short courses, which are free unless you wish to purchase certificates, from Futurelearn, which is an online MOOC, connected to the OU, but offered by universities and colleges world wide.
Sorry if I've repeated much of what has already been said, but I've not read every post.
Well done on your achievements so far, and good luck for the future.
