Got it.
Get some of your local mates to kidnap you for the weekend, make a big fuss and send her pictures of you bound and gagged, then get them to take you to France. Then when she does not pay the £50,000 ransom, it's her fault and she will feel guilty! Of course, when she see's the bank statements with withdraws from France you can say that you had to bribe them to stop beating you and that it was a cunning plan to buy time whilst planning your escape. Your escape came about after being abducted by Aliens who landed at Le Mans Airfield under the cover of the race and the fireworks. They then subjected you to an unrepeatable invasive examination but rejected you as an adequate sound specimen due to liver poisoning, and just happened to drop you back to earth at the end of your street on the Monday after the race.
I have to say that I don't think my wife would buy it, but the utter Bollo*ks value might avert some of the blows.
Hope this helps.
