Sweden is a little expensive but it depends on where you stay and shop. I'm American and studied there in college and have had friends there since that time, so when I go I usually stay with friends and don't always eat out which minimizes the cost. But this time we stayed in hotels part of the time and ate at a few restaurants and other times bought food from the grocery stores or even Seven Eleven. The US dollar was somewhat strong this past summer. If you're in the UK I haven't checked to see how it would be for you, but there are options like the Stockholm Hostel with its private rooms and kitchens which is good for adults where you can get a room for $99 USD per night and then you can eat at food courts and sandwich shops if you're looking to save money there. I love all of Scandinavia, but I'd also like to see parts of the UK outside of London, especially Devon. I'd love to live in Europe. If my husband wants a divorce I wish to move over there except it's hard not having support with a young child.
It's good your husband progressed slightly in his texts. Maybe the holidays will present an opportunity for you and your husband to connect somehow. They can also be a lonely time but maybe your husband will come out of his shell just a bit, we can only hope!
