DB 32, in ordinary times he lives with DPs in the week and his GF at weekends.
I have found out, through social media, that he is still doing this. I raised it with DPs on phone (we live a plane ride apart, but still all in UK) DF mutters to DM off speakerphone and she says loudly, to him that it's none of my business. We don't have a good relationship, I do with DF not DM or DB, who often gang up on me (and other people, it's their thing).
DM is early 60s, and vulnerable DF a few years older and technically not vulnerable but overweight. Both smokers. DB is type 1 diabetic, sent home from work 3 weeks ago to shield and about to start a complex wfh set up today.
DB's GF works at a GP surgery.
I'm furious about the shuttling back and forth, presumably upping the infection risk significantly.
AIBU to worry? AIBU to be cross?
I know IABU to chickenout of a further confrontation on it. I am a professional 40 Yr old woman, who raises delicate matters sensitively for a living fgs, and yet I just don't know what to do here.
