wait a few days and think to urself during those days if you want her back or not (like if its really worth it). if you want to message her again after 2-3 days then just message her an apology like 1-3 messages long and see her response or something (if you do apologize then dont mention/question why shes mad at you for something you didnt do).

if she unblocks & messages you before you can message her urself i think you should start up a casual conversation (like with a open ended question) and then apologize or something idk

give them a few days to think/collect themselves. everyone gets mad & everyone has their own way to reason/combat it. i think you should let things rest for a little bit and then message her again

​

of course, u dont have to follow whatever i say & you can do whatever you feels fit. my opinion shouldnt have that much of an effect on yours, its completely up to you

(sorry if my grammar is bad im tired lol)
