Sorry, this is partly covid related but it's more of a relationships one and I could do with your advice.
We've been coping fine with Covid up until now, not overly worried but following all the rules and being cautious. DH is vulnerable but not extremely, so hasn't been going out, but has been happy for me to go and do the shopping etc.
Over the last few weeks he has become increasingly paranoid. He's started insisting that I shower, change my clothes and don't touch anything or go near the kids whenever I come into the house, even if I have just been for a walk to the corner shop. I've tried to explain that this is unnecessary (I'm a health professional, and all the experts agree that it's not necessary) but he just gets angry and sees it as me not wanting to protect him.
Yesterday it came to a head. We had had a minor argument earlier in the day due mostly to being stuck in the house together with three kids. I needed to go out and pick the cat up from the vets, so went half an hour early to just sit in the car in the car park and calm down. He texted me to tell me that I was putting the family in danger by being out of the house, and when I came home half an hour later with the cat he had locked me out and refused to let me in. After 10 minutes of me shouting through the door he did let me in, but was still insisting that I shower although I had literally only sat in the car (cat handover was done in the car park with masks and distancing etc).
I have no idea what's going on. I can't explain how out of character for him this is, he's normally lovely, calm and level headed. It's really shaken me, and now I'm starting to doubt whether I'm in the wrong. I'm furious and also really worried about him. Help!
