three’s company

My roommate is an administrator at a healthcare clinic. We were both doing social distancing but she announced yesterday that she needs to quarantine in order to keep working. This means that I either needed to quarantine with her in our large 2bdr house and forgo seeing my boyfriend OR leave our house to stay with my boyfriend. (I can't tell if she hates my boyfriend but she refuses to open the door for him when he comes over and never talks to him. Actually, she never talks to me either). The real irony is that she never leaves her room. I'm working from home and I can tell that she spends 10-8 hrs in her room and DOESN'T EVEN LEAVE TO USE THE BATHROOM. How does she eat? Idk but I'm pretty sure she hoards dirty dishes in her room. I can never find enough bowls or spoons in the kitchen because she eats so much cereal. I have 12 spoons (all mine) and right now, there is ONE in the kitchen and its dirty. Every time I come home and see her in the common space, she scurries back to her room and leaves a mess behind. And we have LOTS of common space, even a big yard and deck. My boyfriend, on the other hand, has a studio apartment and a very hyper dog. How are we supposed to BOTH work from home in that small of a space?! The roommate has another thing coming if she thinks that I'm choosing her over my boyf.
