This is a disgrace you wonder what if any qualifications the muppet has if he can't get it into his thick head that you've been out there. What the hell has the timing of your divorce got to do with it
I would book an appointment to go and see your MP at his/her next local surgery. As others have said this forum will be full of invaluable advice - I can't comment as my Mrs was already over here on a Nurse's work permit.
Good luck and don't let it get you down - I'd be thinking of wrecking the idiots job prospects once things are sorted.
