I'm trying so hard not to care but I just... It hurts and pisses me off to see them play hsr. I talked about it.. months ago. Consistently. They showed no interest. They listened to me because I was talking but that's not the same thing. They didn't ask me about it. Didn't ask the name or what the game was about in more detail. Nothing.
I don't normally have to blatantly say "I want you to play this" they just get the game if they're interested so it was valid to assume that they weren't interested.
I distinctly remember talking about something, they came up to watch my computer only because I asked them to and immediately left to sit down after the fact. But now that their friend and coworker talked about it, they have it and play it all the time. And I can't even talk to them about it the last time because they'll just give reasons or excuses as to why they got it after their coworker said something about like they did last time. ("_____ isn't fun to play by yourself" despite me asking if they wanted play said game multiple times and then always saying no)
At the very least I can stop wasting my breath talking about the fixations of mine that you have no interest in enjoying with me.
