If 'she's' over there and contemplating taking on a non-muslim... it's everything to do with the £.. he IS being scammed.
She will do and say ANYTHING to hook him, believe me, I know from experience what women out there are capable of. He's fallen for the oldest trick in the book. I know of the DH of an aquaintence that lost literally all his money to a honey trap, she'd even had reconstructive surgery to trick him into believing she was a virgin... He lost the greater part of £500k in the end.
When I came back to the UK, DH was targetted by 20 - yes, TWENTY women; all wives of friends of friends. Apparently him being a 'rich' man alone went round on bush telegraph. (by rich I mean of course he has a foreign passport, foreign wife and has lived in the Uk for 20 years etc)
Sit him down and read him the riot act and tell him to put his real family first and not some fake one.
In true muslim society, there is NO way on earth her family would accept her shagging anyone, let alone a non-muslim!
If they know about it and accept it, it's that she can pave the way to a new life in the west for the lot of them. Yes, I know that sounds like they are selling her, and it's not far wrong.
Protect yourself, get all the cash you can together to make sure you can meet your own obligations.
