My DB moved in with me, DH and DS in January. He has 2 DC with his EX. During lockdown 1 he went to their house to see them. When lockdown ended and the cases came down, we agreed that as long as they were being sensible they could come round a few nights a week. However on Wednesday DB told me that his DC1 had been in close contact (very close) with someone who tested positive so we agreed that it would be best that his other DC didn't come round either. Tonight he turned up with his DC (one not self isolating) and I explained we agreed that DC wasn't coming round. They both left. DB wasn't nasty but I could tell he was pissed off and now I feel shit as I feel I am telling him that both him and his children aren't welcome, but my gut told me to protect my DS.
Was I wrong to turn them away? I just feel so shitty as rolls reversed i dont think he would do that to me. Sorry for the long post as well.
