My bf doesn’t make efforts anymore like he used to and I’m sick of asking!

I’ve been in a 12-year relationship with my bf (age 26) since high school. Since we began our long-distance relationship 6-7 years ago, he has visited me around every two to three months. From the outside, everything appears to be ideal because everyone in our friend circle believes that we are the “it couple” because we have been together for such a long time. When we were still in high school, we moved through the toxic love stage and began to get pretty serious. I feel loved and secure but at the same time I feel lonely and as much as it may sound weird but I have become accustomed to being with myself and spending time alone. I don’t know whether his living in the same city would benefit me in any way because I usually have to ask him for stuff, like time or items I occasionally want (like flowers or candy). It’s just that I chat to this person on the phone frequently, and that’s it. That has been the situation up to this point. There is nothing about this connection that would draw me in or be alluring or lovely. Even if we don’t talk for a day or two, I feel nothing about it. I don’t get sad or keep on waiting on his texts.

Tl;dr: I’ve made efforts to explain this to him clearly. He simply won’t comprehend or give matters like this any thought. I would then contemplate whether my requests are unreasonable. I enjoy adventures and surprises. However, I don’t feel or go through any of it. Since I’ve been feeling that way for so long, even when I am in a relationship, the idea of being single feels incredibly normal to me right now. I don’t know what to do.
