That's really sensible of you not seeing your parents - wish everyone was thinking along those lines. I would just be honest with your boyfriend and say you aren't comfortable with visiting his family, you can always say it's down to having vulnerable parents / grandparents yourself and if you "had" to go visit yours then you don't want to carry extra risk to them.Can't believe they are planning to let a few houses form a bubble for a whole week over Christmas Christmas Eve is one of the busiest days at my work out of the whole year. So all those people mingling potentially catching it. Then going to spend a week with their elderly relatives and another household. Lockdown 3.0 in January then! If it's legal I can't exactly say no very easily to visiting my boyfriend's family. I'd already planned not to see mine, they are caring for my grandma and mum is vunerable. I've seen them approx twice since Feb just from outside and at a distance but it's fine as I know I'm doing so to protect them.
