AITA for not wanting to buy something my fake friend is forcing me to get?

So, I (13M) have a fake friend who has been treating me badly for a while now. He used to be close to me, but lately he's just been using me and bossing me around. Recently, he started yelling at me, saying things like, "YOU WILL BUY THE PRIVATE SERVER, OKAY?" because he wanted me to get a private server in Blox Fruits to help him and others get V4.

The thing is, I had my own plans. I wanted to save my Robux to buy bonds in another game I love, Dead Rails, to unlock a new class. That’s what I was excited for. But instead of respecting that, he acted like I owed him the server. He didn’t offer to help pay for it or even ask nicely — he just demanded it like it was his decision, not mine.

Now he’s making me feel guilty because I don’t want to spend my Robux the way he wants. I worked hard for it and have my own goals. I’m tired of people using me just because I’m nice.

So, AITA for refusing to spend my Robux on what he wants and wanting to use it for myself instead?
