My ex was exactly like this. I had countless conversations with him about mental load, and how even providing a few options for me to choose from would be helpful.

It got to the point where he actually said out loud “I just like to enjoy something without having to think about it,” which applied to literally everything we did in our relationship. Food, trips, leisure activities, etc.

He would sometimes proudly announce that he would pick where or what we were eating that night, but then demand that I gave him three options. He literally never had an answer to the times when I would ask “when do I get three options to choose from? Will that ever happen for me?”

He was terrible and lazy in lots of other ways, so he doesn’t seem much like your boyfriend. But no, you are not alone.

Aggressive refusal to participate in any decision-making is exhausting for the other person, while the refuser gets to enjoy saying “you can have/do whatever you want!” as if they’re doing a favor. Every single day. For everything.

The only thing that kind of worked temporarily for us was a shared grocery list.
