That’s not true - you have to be double jabbed to get into the states if you aren’t a US citizen and also have to show a negative test aswellThe US completely opened their borders early November even to unvaccinated travellers- you now just need to show proof of a negative test. And whilst LA does have stricter vaccine mandates than other states, there are plenty of places that do not require proof- for example Disneyland has stated it strongly suggests that people be double vaxxed but won’t actually be requiring people to show proof.
Long story short, if they wanted to be together in LA…they would be together in LA, it’s not some moral high ground of Jay not getting vaxxed that’s keeping him in the UK. I think they’re perfectly content with their lives the way they are. She gets to hang out with the kids 24/7 and he gets to hang out with his lads and dip in and out of family life for things like birthdays and celebrations.
