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 next Saturday's paper.
This week's question:
My cousin lost his job, can't afford his mortgage, and wants to stay with us for three months. We have the space but my partner fears the instrusion. I feel a moral obligation as it will get my cousin out of a financial hole. It's causing big rows. Can I – should I – insist?
What are your thoughts?
