My bf (M29) replies to my (F29) replies really late to my texts

so when i was in the same job as him he used to freak out or get angry if i didn’t reply within an hour or so, now i am no longer in that job but i do know we can use our phones all the time and i know the nature of the job and it’s definitely not a busy job lol but now that i am no longer in the same job he takes his sweet time to reply aka replies after hours and if i ask him where he was or what he was doing he get extremely angry. isnt that weird? also what do you think is the right turn around time for a text? also he has a problem in letting me know if he will be gone for a few hours idky. he says well do i have to tell you everything or what, which is so weird because i lowkey wanna tell him everything about where i am and what i am doing to make him feel secure in this relationship or just i wanna tell him stuff about my day but he never wants to really share anything unless i poke him.
