I usually wfh, dh usually works in an office in town. I am used to having the whole house to myself, in peace and blissful silence. Not anymore.
We have both had to adjust. dh had to adjust to not having colleagues in the same workspace. I had to adjust to having a noisy presence in the house how can anyone make so much noise typing on a keyboard?
It's different issues for both of us, but we keep communicating about it, and are clear about what works / doesn't work. In the first week dh would appear in the kitchen at 'his' lunchtime looking expectantly for lunch. Nope. Not going there. Not rearranging my day around his lunch breaks. In 'normal' times he is responsible for his own breakfast, own lunch, same rules apply. And we discussed it (which I think is important). Even now 4 months in, dh sometimes looks enviously at my colourful lunch plate, which is usually some kind of leftovers with loads of salad, while he stares mournfully at his beige sandwich and crisps. We both have equal access to the fridge / cupboard ingredients, I'm just more inventive in my choices.
I've also been clear about how much I value my own space. Of course I can go out to get it but it's not the same as I am used to. Sometimes when dh goes to visit his parents I opt not to go, and I enjoy the luxury of having the house to myself. He is currently away for 2 days, and I have chosen to stay home. In 'normal' times I would have joined him on his trip because it would have been valuable together time, now the alone time is valuable.
The important thing is that we talk about it, how the different circumstances make each of us feel, and how we can each create what we need. If your dh needs companionship, how can he create that without relying on you? If you need space, how can you create that in a way that doesn't make him feel unwanted?
