Would you be mad?

Last year I bought me and my boyfriend these tablets with MY money from working on amazon for $20 plus shipping. I saw a cool YouTube video about them and wanted to try it out with him. When you melt it on your tongue it turns all bitter things sweet (for example it makes lemons taste like lemonade). My boyfriend and I tried it and it really works. We only got to try it once and it came with 10 tablets. I told him I wanted to do it with him again in the future because we didn’t have enough foods to fully experience it so I left them at his house. Today I told him I wanted to try it again with him but he told me he gave them away. He said he tried it twice with two of his friends (that I’m okay with) and then gave the remaining 4 tablets to his neighbor because she went through his drawers and wanted to try it with her girlfriend. I told my boyfriend that it hurts me that he would give that to her because it wasn’t his to give away, I was the one who paid for it and he knew I wanted to try it again. He also gave this same neighbor a journal I bought with my money for him while I was on vacation. He told me I need to learn my place, I have no right to be mad because he gave it to them months ago and I need to learn my place and quit nagging at him. Also, during this same time, this girl and her girlfriend were telling my boyfriend to break up with me and that me and him aren’t “twin flames.” Would you be mad about this?
