It's all a bit of a long story, but in short.... My Dh and I have spent every year with her since we have been together.We have always got along really well, and DH adores her. Over the last few years she has borrowed money from us, and we had given her a credit card to use. All the money was supposed to be paid back at the begining of the year when her investment matured. We have waited months with various excuses as to why the money is not in yet. This week we kind of ambushed her asking for proof that the money exists. Turns out... She has been lying the whole time! My BIL wants to disown her. Dh and I are furious as we will have to sell our house to pay off the £20,000 debt she has run up in our name. I am still trying to help save some kind of relationship between her and my dh, because He loves her so much and for the sake of my children, but I don't think I want her here for christmas! AIBU?
