Buster, I can't help thinking you shouldn't have moved out. Not because of the Covid19, but because this is a familiar pattern in your household, but this time it's under incredibly difficult circumstances. Do you think you just give in to a bad situation letting your partner win? Why could you not be in separate rooms while the air calmed down? I think your partner left last time and that wasn't that long ago. And then somehow you manage to make up your differences. As this happens so often I can't see why the both of you just sleep on it for a day or two until you get back to that point again. And as it does happen alot, the thought of a sofa bed springs to mind.
I also can't help thinking whether you will be still doing this in 10 or even 20 years time.
I'm just being truthful Buster. Unless the pattern changes, your situation won't either. Your partner knows the game and you just move the pieces to accommodate her letting her win. Think of you and your health buddy. x
