A man I've been dating for the last 10 weeks (so not boyfriend or anything remotely committed) text yesterday morning to say he'd tested positive with covid and was feeling awful and getting into bed with his electric blanket on and all his clothes on. He was last online at 2pm and hasn't replied to my last 2 messages. This morning I thought I should call him and he didn't answer. I'm starting to think he might not be ok, he lives alone and I don't know any of his friends or family who could check on him. He's been asleep for 19 hours with no contact and possibly overheating.
Any sensible suggestions for what I can do?
