Is this even legal?

I don’t thing legality comes into it.
We are recommended as to what we can do.
It sounds to be unwise and I hope your H takes every precaution to protect you when he comes home.

It’s about being sensible now, and if you are not happy, it’s perhaps not a good idea.

You can have gatherings up to 30 outside from next week, and I assume he is going to chat in the garden and not kiss them all? If he is sensible, comes straight in and has a shower and puts his clothes in the bin, it should be fine, but talk to him about your worries and see if you can come up with a way for him to meet them all that you are both happy with. He needs to see them. If you rant at him, he will just takes more risks out of stubbornness if he is anything like mine!

You are correct, only two households can meet together indoors after the 4th July but up to six people can meet outdoors.

It needs everyone to follow the rules if we are going to reduce the spread of the virus. It annoys me when people say it's OK to ignore them if you are "sensible" or " use your common sense" or they are " only recommendations and do not need to be followed" or " well, it's only once"

I am not scared of mixing with other people again but would feel more confident if there was not this big rush to get together in large groups again, I'm happier taking it slowly and waiting for the impact of each change to be seen.

thanks so much all, I don't think they are meeting in the garden because his mum is too poorly for that at the moment. I will ask him to shower & wash his clothes when he gets in & I'll sleep in the spare room for 2 weeks. When I speak to him about it he just says 'it'll be ok' and its just bluster, he can't know that. Hooray I've just had a text from him and he's going to ask his 'children' not to come! I'm delighted, I do love his family but I don't like being put at risk. Thanks so much for 'talking' it over with me, you were a great help
