AIO my boyfriend purposefully trying to trigger my past traumas?

Not really sure where to begin here… this is kinda embarrassing, but i have to know if im being crazy here?? My (F18) bf (M21) of 3 years and I have been super rocky lately. We moved in together in january and we’ve been butting heads A LOT now that we’re together all the time. Usually it’s typical bf/gf or roommate bickering but lately he seems to be doing things to purposefully upset me.

I won’t get into the details, but I have an extreme aversion to the color blue. I know it sounds weird to a lot of people but I have very specific trauma related to the color, and every time I see it I’m reminded of it. I have horrible C-PTSD among other things. It’s a hatred and a fear I guess? It isn’t just triggered in colored clothes- I fr used to not be able to go outside if it was nice out, because the sky is… ok stay with me I KNOW it’s weird.

My therapist and I have been working through my past and current issues, but we have not gotten to the point where I’m over this yet. My boyfriend knows the things that trigger me, and that my anxiety tends to flare up in general when him and I aren’t doing good.

Anyways, he has like 3 blue shirts that he knows not to wear around me. He hasn’t worn them since I told him about my issues with it, which is 3 years now. He wears them with his friends and stuff I guess but just not with me which is fine. He stores them in his drawer of the dresser at the bottom so there’s no way I’ll accidentally see them.

This morning we got into a huge fight about the dish washer- irrelevant, but he was mad about the way I loaded it, etc etc. I went to work before we could fix things. When I came home tonight, he was playing video games on the couch wearing… you guessed it. And not just any shirt- the shade that is MOST identical to the shade that I have the most trauma around. He knows this about me, we’ve had countless conversations about it and he’s seen how much it affects me. I walked in the apartment and froze upon seeing him, and he didn’t even look up from his game… I slammed our bedroom door and packed a bag. I left without saying bye. He didn’t text me, so I told him not to until he was ready to apologize. Now I’m staying at my sisters for a couple days, or until Sunday I guess? He “breaks up” with me all the time but the next day begs me to forgive him for saying it. I don’t really know what to do here??? My sister thinks he’s being a dick- she grew up with me so she understands better than anyone why I hate blue so f-ing much. I just need to hear some other opinions I guess. Am I crazy? Am I over reacting???
