thank you for your quick answer.
that is a blow, more to my pride than anything else! I had originaly planned to pay him back by remortgaging - we were to sell both our properties and buy somewhere new together.

Okay, thank you, Jo. Much appreciated. Not what I wanted to hear, of course, but much appreciated anyway.
