I understand how you feel and I would feel exactly the same way if someone was in my house. I would find it awkward to go out of my room and have to deal with another person being there, feeling like I should make some kind of conversation or just not knowing how to act and feeling self conscious. It's been a long time for me, but I have had someone staying at my house at different times. Can your husband act as a buffer? Or is he not there a lot of the time? I'm sorry I don't really have any advice. I feel for you.
