Every week a Guardian Money reader submits a question, and it's up to you to help him or her out - a selection of the best answers will appear in Saturday's paper.
This week's question
My best friend recently met a new girlfriend and it's got very serious, very quickly. I've now discovered that she's borrowed quite a lot of money from him. She's attractive but something's not right. I fear he's being taken for a ride. Do I warn him, or stay out of it?
