*I don’t understand why you didn’t just say to him “okay, it might not be a problem for you but I want the house to myself so my friends can come round and we can have some space, so please go to the office on X day. I want to spend time with them without you here”.
Is this a thing? I have a full house of numerous adult children and a DH, now all a combo of WFH full time, WFH part-time, studying at home full-time, studying at home part time.
In no world do we make some weird roster to ensure only one of us are home at the one time, dictating everyone else must be out, so we can invite friends around! If we want friends we invite them. The reality is there will be others home, and as we are a packed house with numerous adults, chances are there will be quite a few people here. I can’t think of a time where any one of our ‘general common’ areas (not bedrooms) wouldn’t either have someone else in it doing something or people walking in and out for whatever reason. We don’t ‘spy’ on each other, we don’t ‘control’ each other - it’s just living with other humans. You can’t ask people to go hide in their rooms because you want friends over FFS, how very odd!
I’m not getting the issue. If you wanted friends over just invite them. Do whatever you want around your DH. If it’s an issue for him, he can take himself out. If it doesn’t bother him he stays in-situ. Problem is what?
