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?

Financial matters can get uncomfortable if things haven't been settled prior to combining assets upon getting married. For me, in all cases, I will help my in-laws the exact same way I would expect my husband to help my parents. We marry into families and we take the good with the bad.
