AITA for refusing to let my in-laws live with us after they lost their house?

So, my husband (33M) and I (30F) bought our first house about a year ago. It’s a modest three-bedroom, and we’ve been really happy with it. A few weeks ago, my in-laws (both in their 60s) came to us in tears and told us they’d lost their house due to some bad financial decisions and didn’t have anywhere to go.

They asked if they could move in with us until they got back on their feet. At first, I wanted to help, but then I realised it would be a huge strain on our home. We already have a young child, and having two additional people living with us would completely change our dynamic. Not to mention, my in-laws have a history of being incredibly critical of my parenting and lifestyle choices, which has caused tension before.

I told my husband that I wasn’t comfortable with the idea, and that we needed to discuss other options, like helping them find affordable housing or connecting them with resources. He was disappointed, and now his entire side of the family is calling me selfish and saying I’m “breaking up the family.”

AITA for refusing to let my in-laws move in with us, or should I have just made the sacrifice?
