Hi David
I’m in the U.K. too and going through a similar-ish situation
Your wife has no right to take the children, my solicitor advised me that as my wife is making the move for D and also looking for a house, it is totally in our children’s Best interests to stay in the family home.
My W has turned from a kind loving woman who I’ve been married to for 11 years, to an absolute monster in just six weeks, including the past four months spent in a well known London psychiatric hospital, where she was treated for anxiety and depression.
She was discharged yesterday and ive stupidly let her stay in the MBR until she finds a house to rent.

I hope we can support each other during this absolutely awful experience
Best
