Husband at home

The current pandemic means my husband is home from work. I really don’t like the current situation and I am having so many thoughts that are not helpful. I’m struggling with my R line.
C: husband home
T: I wish I was alone
F: Irritated
A: Short with husband, limit conversation, keep airpods in ear when I leave the home office for kitchen.
R: ? Spend more time alone in my office. Distant relationship with husband (not a change; this is usual).

I’ve just always enjoyed my alone time. I hate that every time I exit my office for a snack or a drink or to eat lunch he’s right there asking me a question, making noise, working out, whatever. I feel like I have no privacy.
