We have some financial issue this month. My husband want to lend some money to his parents but i don't think that's a good idea. I prefer we sell some stuff to cover our financial rather than lending money. How can i say this to him without hurting him?

It is always tricky to deal with household finances, especially where in-laws are involved. If your husband is supportive and understands you then it's better you talk it out with him and give him your suggestions. In case you feel, he may get a bit defensive because the issue also deals with his parents, be super careful and still share your opinion with him, perhaps suggesting a better option (here, to sell your stuff). It will be difficult to convince him immediately but that's exactly why you must act as the voice of reason.
