AITAH for my husband losing his expensive watches

My husband of 8 years has suddenly decided he needs to wear his nice watches for a family wedding next week. He has never worn a watch in all the years we’ve been together. Two years ago I got pregnant and we needed to clear out a bedroom for our daughter. The room was full of bins with his stuff that he hadn’t looked at or touched since we moved into our house (several years). He claimed he was “too busy” to look through his stuff so I had to do it all myself otherwise our daughter wouldn’t have had a bedroom. I moved his boxes either into our attic or basement and he knew all this. Now he has to find these watches and I don’t remember the exact box they were in bc it was 2 years ago. He’s now blaming me and saying he has to go buy a new $500 watch. I suggested Amazon but he won’t listen to me and keeps ob over the lost watches. Now I’m exhausted after a full day of taking care of our 2 girls on my own with no break (the older one doesn’t nap anymore). AITAH for being angry with him and refusing to help him look for these watches bc I want to sit and have a moment to myself?
