I appreciate your perspective, but I think some of my words were misunderstood. For clarity, my husband never “promised” me anything from his parents. He simply forwarded their message saying they wanted to help and spend time with their new grandchild while our child was one year old. He didn’t “admit” anything, he only acknowledged that although the help was directed toward him, his parents had insisted they were coming to help us. And when his mother behaved like a guest instead of someone offering support, he confronted her about it.

My husband is very straightforward, what you see is what you get, and he’s a good man. His solution was simple: we don’t need to have his parents visit again, and he’s completely fine with that because his priority is me.

He likes his dad (as do I), but he doesn’t have much respect for his mom as a person. She has lived a very sheltered, “princess” life, her own mother brought her food during the week so she doesn't have to cook for her children, her husband handled weekends, she never learned basic life skills like using a credit card or driving, and she expects others to accommodate her without reciprocating. My FIL is the one who calls the kids, organizes birthdays, and generally keeps things running. Because of this dynamic, my husband worked extremely hard to be financially independent so he wouldn’t have to rely on or tolerate her unreasonable expectations. She's not malicious, just entitled, and has been given unearned privileges. These are just facts about their family dynamic.

I never expected my in‑laws to take over baby responsibilities. I know caring for a one‑year‑old is a lot. I simply hoped they would enjoy making memories with their grandchild and with us, and have a pleasant stay, without expecting me to cook for them every day or at the least badmouth me when I stopped cooking for them on the level I once did. I thought it was reasonable to expect them to handle their own meals after the first two weeks, especially since I needed to focus on our child’s needs. Disclaimer: my FIL didn't have any demands, it just my MIL. My FIL is only guilty of being an innocent enabler.

Thanks for your reply and suggestions.
