AITA for gifting daughter presents meant for husband's side piece.

Back in 2018 we went on a Christmas trip to see my now ex-husband's (Joe) sister (Jill). He was acting strange and would not talk to me. His sister whom I only met 1 time before ignored me. We had present sent to her house so we did not have to pack them. I was wrapping presents and Joe and Jill went outside for an period. He would not tell me what they were talking about.
When we went to pack up Joe was very concerned about his backpack. Only he could touch it. I thought this is odd but whatever.
A month prior to leaving I found a prepaid card in his wallet. I took it to see what he would say. He asked about it and said it was for work. I "found" it and gave it back to him. About a week later I asked if he was having an affair. He said no and I dropped it. We have not been in love for quite a awhile and I knew we were heading towards divorce.
Upon return from trip something told me to look in his backpack. So while he was is showering I looked and found 2 bracelets and a gift bag I took the two bracelets and hid them. All was well until he went to car to leave. He came storming in demanding I give the bracelets back. I simply replied "what bracelets ". He said he bought them for me for our anniversary next month. He knows I don't wear bracelets and actually hate them. Why would he be freaking out if the bracelets were for me a month later. He storming out and we didn't talk about it again. I was finally able to get in his phone and discovered texts messages confirming the affair Part of me didn't care because we were not on love, but I still felt betrayed. Two years later we are divorcing. I am cleaning out our rooms helping him pack. We had a very amicable divorce. While cleaning I found the two bracelets I had hid years ago and forgot about. I didn't want them but our middle child (f15) loves jewelry. We were separated but decided to have Christmas at the house together. So Christmas morning comes and kids are opening gifts. The look on Joe's face as our daughter opens the bracelets was priceless! They were rose gold- her favorite! Her face was beaming with joy. He sat there looking at the jewelry like a deer in headlights.

So AITA for gifting jewelry to my daughter meant for my husband side- piece

EDIT: some have strong feelings about gifting bracelets to my daughter and her feelings if she finds out. I have no intention of telling her. Joe will not say anything. He denies the affair completely when talking to other people. He has also since abandoned the kids. He moved out of state without telling them and only contacts them on Holidays and birthdays. The only way she would find out is if I would tell her.
