AITA for not letting my brother in law eat a slice of our wedding cake?

I'd like to preface by saying this was a unplanned, spontaneous reaction from me and i'm starting to regret it a little.<br><br>This happened some 5 years ago when I got married but it still comes up in my family from time to time. Also, please don't come after me for my baking, I had no clue at the time what I was doing but I put my entire heart and soul into making it and spent many hours into perfecting it.<br><br>So back in 2018, my now wife and I finally got married after being together for a long time. This was our first and only wedding as we were both in our early 20s and our budget was tight, so we spent a lot of time making sure everything was perfect and by hand. I, being the idiot that I am, decided that I was going to bake the wedding cake myself. I spent months perfecting the design, recipe, etc. and was still a beginner at the time. It was far from perfect but everyone at the wedding complimented me on how good it tasted and looked. It was a tiered cake with 3 layers. My wife and I each got a slice and we gave the remaining portions out to our guests. <br><br>We had a few remaining slices left over at the end of the night and brought it back to our new home. We decided that we'd eat a slice on each anniversary and leave one for our first child. This was a little tradition we decided on, and I was more than happy to because i really wanted to preserve that memory by eating a piece of my own wedding cake every year for a long time. <br><br>Fast forward a year or so, My brother in law comes over to our new house to help us with some moving. We were in the process of moving to a bigger house and he offered to help us move because we were short on help. While he's walking through our kitchen he notices the box of wedding cake in the freezer and says, "Oh, you didn't eat the rest of this?" <br><br>I was extremely proud of this cake and wanted to preserve it so I said, "nope, saving it for the memories" to which he replied, "well I could eat that now" in a joking manner. This is where the conflict started. Without thinking, I immediately replied "no, you're not eating my wedding cake. That's forever, not some afternoon snack." He was taken aback by my reaction. <br><br>Then, a few weeks later at a family gathering my SIL and BIL are telling my family that I got mad when he wanted to eat a slice. I elaborated on the whole thing but they seemed to be on his side, saying that it's just cake or he was just joking. I got light backlash from some of the family and some said I was right in preserving it but they thought it was a little overboard. <br><br>Edit: To answer a few questions.<br><br>1. It was frozen after the ceremony and we left it in the fridge for 24 hours before freezing it. It's still frozen to this day and we just eat a slice every year. It's held up surprisingly well. <br><br>2. A few people are mentioning termites and bugs. We keep the house spotless and have never had any problems like this. I don't understand how people let this happen to their food?<br><br>3. I understand leading someone on and giving them false hope. This wasn't my intent, but I can see why he would take it that way. <br><br>4. There's no way in hell im selling it. If anything, the conflict and backlash from family just solidified this cake's importance. It'll be taken to my grave.<br><br>Edit 2: I'll stop updating this once and for all, but I feel the need to address the amount of uneducated comments I'm getting about frozen food. Yes, some foods are not made to be frozen, but there is a whole science behind cryogenic freezing. This cake is not going to spoil any time soon. <br><br>Thank you to all the support and constructive comments on this thread!
