Has his family ever asked for help with anything? If so, would you feel comfortable with helping them out as your husband has been willing to help out yours (even though you didn’t ask)? I would respond to your husband’s words that if his family ever needed any help that you would be willing to help out as he has done for yours. It’s just fair. But also all decisions to help someone money wise, especially if your finances are shared should be made together. So it’s not just you “sacrificing” - I like the word “helping” better - but you BOTH as a couple.
