DP’s younger sister split from her DH and asked to stay with us. We have a joint mortgage on a 2 bed maisonette. Of course we said yes.
That was 9 months ago. She hasn’t offered to contribute financially, but does cook a meal for us all several times a week. It turns out she was in a lot of debt and has been working really hard to pay it off and is doing really well.
But DP and I also have debts and I feel uncomfortable when she tells me how much she’s paid off. (I would have no debts either if I lived rent free with heating, internet etc on tap. It would do wonders for our finances!) I get on well with her but do miss having a spare room and our own space. She also has a new boyfriend who she keeps inviting to stay over.
Things aren’t helped by DP constantly remarking how generous she is for cooking, and he buys her things / meals to say thank you! He doesn’t seem to realise that we are already doing her a big favour. I don’t know how to raise this as DP’s sister is lovely and had a really horrible time last year. If I do say anything at all DP gets very defensive.
I guess I’m just looking for perspective as I would just like her to pay her way - she’s 33 and an adult - but need to know if I’m unreasonable and advice on how to broach it.
