My daughter, son in law and grandson are visiting from abroad for a month and renting a house. Her dad is staying in the house with them so they are all one household. We are in Tier 2.
I live with my adult son who is not sociable and basically stays in his room all the time. We both work from home, him in his bedroom, me in the living room. I am usually in a support bubble with my bf who lives alone. Since my daughter has been over I've barely seen bf (couple of times for a couple of hours chat) and have been only socialising with my daughter either outside or at her house, and babysitting my grandson etc. Effectively our households have been one bubble and I cut down seeing bf because I was seeing daughter.
She has met friends outside but for the last week has been very careful not to add any extra contacts, even outside, because of staying safe for Xmas and because of the new strain.
The plan for Xmas was for my household (me, adult son plus my bf) to go to their house). Relationship with bf is coming up for 4 years but on its last legs. Usually we spend it together, this year he was going to go to his parents while I spend it with my daughter but his parents are now in Tier 4 so that's off. So I said well rather than be alone, come and join us, that's 3 households as my bubble. And I said we should all be extra careful in the run up to Xmas and it would probably be wise if he didn't go to the office or other places if he didn't have to.
Last night I couldn't reach him and it turned out he was at a woman's house, indoors, windows closed, talking. For several hours. I think that's a bit off to start with, this woman is a friend who has always been keen on him but he has always been adamant he is not attracted to her in any way at all. I didn't even think he saw her except if they bumped into each other for their mutual hobby but a few months ago it turned out he saw her quite regularly as a friend but had never thought to mention it. I said at the time it was just odd that he didn't mention it in conversation because most people would. Anyway, more importantly, we are not meant to visiting people indoors at all. Would it be unreasonable of me to cancel him coming for Christmas because he spent yesterday evening with this woman? I don't want to come across like I'm punishing him but he could potentially be putting my family at risk, and if he has mixed with her and she with him, who else have either of them been mixing with? My daughter's dad, although staying with her, is also caring for his dad who is elderly - not close range but doing shopping and stuff.
I'm not at all paranoid about Covid, I've had it myself mildly but I have been really careful all the way through, and when my daughter came over we agreed to be very careful that even though we saw each other, we kept contacts down, even though she wants to catch up with people she hasn't seen for two years, so I just feel like him doing that was disrespectful and really off.
