Would moving back to London be foolish?

[OnWednesdays]

I moved out of London several years ago with now ex-dp and two small children. It’s not be an easy time, but things now are good. the DC (7&4)and I now live near family and have a great quality of life. They spend time with their dad, not quite 50/50 but not too far off.
I have a wonderful relationship with a new man. He’s based in London and no opportunity to move out with work and commitments. I really miss being in London and am there often as a visitor. I have a property which I rent out, but the DC and I could happily live in it…not forever, but certainly for the next 5 years as a minimum.
I’m considering moving back. I miss friends, the sense of potential, galleries, museums, music, big parks full of people, work opportunities and my property.
would I be mad to move us back? They would have to move to new schools, they would be further from their grandparents, the situation with their dad would need to change…that all feels scary but workable. But I would then be a single parent without family support, in need of a new job, and filled with guilt about uprooting them again.
Any thoughts anyone?

I understand the pull of London but if they're settled in school, have equal time with their dad and a close relationship to wider family I'd struggle to make the move if it was me. Don't put your relationship before the children's stable life.

How far from their other parent would you be taking your kids?

Sounds like an awful lot of upheaval for the children. Would you still be wanting to live in London if the new man loses his shine?

NO. All that upheaval off a man.Its ill thought out madness. Kids first, not new man first
If its a serious relationship can he relocate to you, get a rental, see how things go
