My partners son (10) is currently isolating due to his mother having covid. Partner is not able to see him for 10 days, he usually sees him every few days. My partner has said that he wouldn't feel right coming over to mine and spending time with me and my son (also 10) whist he's unable to see his own. I don't really know what I'm asking, I'm just feeling a bit upset and I'm not sure if it's justified?
