So context: I WFH all day, did 2 hours of dog walks, gym then went food shop - didn't stop all day. Partner was off work, slept til 11am, played video games all day with friends until 7.30 when dinner was about ready.
We sat down for dinner (grazing Infront of TV) and afterwards when I finished (he was still eating but a picky dinner). I picked up my.phone to text my sister back. He gave me a very obvious scowl (a well known look for me to get off my phone) and I said to him "I am texting my sister back quickly, I think that's fair and you've been chatting to friends all day". His response was to "watch my lip". I feel f*cking annoyed tbh. Like it's ok for him to do what he likes but I'm a child to be told off but maybe I am seeing it irrationally. AIBU?
