Me and my boyfriend have been together for years and I feel like he doesn’t know me. Tonight we have been out for mine and my sisters birthday meal and she LOVES fuss, I on the other hand do not. I knew something was going on and found out he arranged for a cake and for everyone to sing happy birthday but this stressed me out so much I excused myself with feeing sick and left beforehand. Now he’s upset that I left and I’m upset that he would arrange such a thing knowing how uncomfortable it would make me. AITA for leaving?
