’24 F’ have been struggling to express myself to my boyfriend ’23 M’ without him shutting down on me. What’s a better way to approach the situation?

I ‘24 F’have been in a relationship for over 2 years ‘23 M’. I will say this relationship is a roller coaster due to the adventures it takes me in. My boyfriend is autistic and selectively mute, which usually gets triggered with anxiety.

I’ve had to deal with a lot of patience since whenever he shuts down, he can’t talk because of his anxiety, so I try my best to always uplift him and let him know I am here for him. I will say I get frustrated sometimes, and I do try my best in apologizing because I have to also understand it’s not his fault. Well, lately I feel like he enjoys seeing my emotions, whether it’s negative or positive, and as an emotional person, I do show them.

So today I was bored and wanted to play Fortnite, in which I’m really bad and he isn’t, but I enjoy playing it especially with him. He wanted to join me on a creative, so I thought why not 1v1 since we tend to have a blast even doe I get destroyed by him. Well, for some reason, he was kinda annoying me because he just kept using overpowered weapons and killing me in one shot. I got annoyed so I told him how it made me feel but he was laughing at me raging so once I said “stop it or else I’m going to hang up” he then kept mocking me and repeatedly say “nana na boo boo” in which I hung up but he would sent me text saying the same thing and was saying it on game chat…

I was getting fed up because I felt like I was being made fun of, in which I joined back into the call and told him, “Stop it, you’re annoying me, like I’m not having fun.” he then shut down and left the call. This has been a repeated cycle where he pushes my buttons on purpose and I tell him he’s upsetting me, which then always leads him to shutting down and not wanting to address the problem…

I sometimes feel like I’m walking on eggshells because even if I start expressing what makes me upset, he just won’t talk to me until he’s ready to talk, and when he’s ready to talk, he wants to not address the topic. I really need some advice on what to do I’m genuinely at my last straw and I’m lost on what to do.
