Am I Wrong?

Every year my bf and I buy flowers for our backyard. When I say “we” I mean me. I always go out, buy them and plant them, and every year my bf says, “buy whatever you want. Decorate it however you want.” Every year I always buy the same red, pink and white flowers and every year it looks the same but this year I went to a new garden centre and they had different stuff. I ended up with similar looking flowers but instead I got red, purple and black (not normally something I would buy but I really wanted different this year and they looked fun mixed with other colours) I came home, planted them all myself and then my bf takes a look at them and got so mad at me for buying black. I tried to explain that I was different and would look fun but he was not having it. I reminded him that he told me I could get what I wanted and especially when I was doing all the work myself that I was going to get something that I wanted. He told me he only says that but doesn’t actually mean I should get what I want. I should be thinking what would he want.

Every year I ask if he wants to come and help pick them out and plant them and every year he says no.

I think he is being ridiculous for getting so mad at me over this. I bought what I wanted, I was the one doing all the work, if the role was reversed I wouldn’t be mad at him buying what he wanted especially if I was refusing to participate.

Now he is beyond mad at me, saying next year he will take care of it because he can’t trust me with buying flowers.

Is he right? Should I have bought what he wanted? Ignoring what I thought would look cool?
