Need help picking anniversary gift

Meme

Hi! Okay so let me start by saying I’m a very closed off person so this is new to me. Anyway, my boyfriend and I have been together for almost three years. We’re both 18 going to turn 19 this year. Our three year anniversary is on 02/24 and I want to get him a gift but he really doesn’t like it when I buy things for him, as a matter of fact... he hates it. He thinks he should spoil me because of how my ex treated me and how I’m still mentally affected my it. He is sweet when he wants to be, we are goofy together and I really do love him. I don’t know what I should get him since he doesn’t like a lot of stuff. I was gonna make him a photo album of us but he doesn’t like taking pictures unless I ask him too. I’m so confused on what to get him. Please help

P.S. if it helps, he’s a gamer but I’ve already bought him something from his favorite game.
