AITA for reorganising my library while pregnant and telling my in-laws my husband wouldn’t help me?

I’ve recently had an almost obsessive urge to reorganise everything in my home. My library is one of the places I felt needed to be changed asap so I asked my husband multiple times if he would help me as my shelves are pretty high up and I have a lot of books that are heavy to move. He kept telling me he would help me later as he was busy.

It felt like later was never coming so I finally decided to just do it myself while my husband was working. My in-laws came to visit us and they walked in on me grabbing books from the higher shelves. They thought what I was doing was dangerous and that I could’ve fallen. My husband also freaked out and kept telling me to get down and saying I shouldn’t be carrying heavy things.

My father-in-law asked me why I hadn’t asked somebody else to move my books for me and I told him I did ask my husband but he wouldn’t help me. He did try to correct them that he said he would help me later but his parents told him off for not doing it for me.

He thinks I made him look bad to his parents and is upset that I didn’t correct them and because I didn’t wait for him to reorganise my library. We keep arguing because I told him that he didn’t help and that I didn’t want his help anymore and I would finish the library myself.

AITA?
