Wow, Gillian. My wife and I are also introverts ("We just hate people," as she likes to say). I love my wife dearly, I love that we're stuck in the same house for all day every day since March, I love spending time with her... yet even I enjoy those days when she takes a few hours away to spend time with our young grandniece to take the pressure off our niece (and I know my wife feels the same, getting away from me). We've discussed that even traveling with friends & relatives is wearing on us, never mind 24x7x[day n of the pandemic] in the same place all the time. I hope you find a way to relieve the pressure and become more comfortable in your home again!
