I'm with ya there matey. One of the nails in my relationship coffin was when I told her my R&D gearbox was £500 (and she thought that was a lot) The fooookin roof had a dent in it when she happened to see my credit card statement and it was really £5,500.
Another one was popping to Stu's for half a day to get my map looked at and I ended up staying for 5 days.
It wasn't all one sided though, I kept her in 4 bed detached's, brand new cars and more "Jimmy Choo's" than she could shake her 20 trillion DKNY frocks at.
Being single rocks though in my opinion, I had totally forgot what I had been missing.
