work from home woes

On Thursday evening, my husband and I got into a fight and he stopped speaking to me, so we barely talked that whole night. On Friday, we both found out we would be working from home starting Monday - him for the next two weeks, and me indefinitely. We still didn't talk on Friday after work, and we didn't talk all weekend. Now it's Monday morning and he set up his computer RIGHT ACROSS from me at our dining table (we don't have much space at home). He didn't test out his VPN so he's calling his office's tech person to get help, being very loud on the phone, sighing loudly in frustration while I'm trying to compose emails and get my work done. I don't know how to do this for the next two weeks or more.
