how would you feel? please help.

long story short i was bullied in highschool. my boyfriends best friend since seventh grade engaged in this bullying and would tell him constantly to watch out for me or warn him to be weary of me before we started dating. she doesn't respect the boundaries i've set in place and ive let him know about this. this would be too long of a story to bring up what she's done while we are together. for context he moved away, she also moved away and goes to the same uni and lives on campus near him.

we have had multiple conversations regarding her, many of which he refused to do anything about being friends with her or the situations she's caused. again, long story short, he essentially told me to deal with it and that he'll be friends with her no matter what.

again, this is someone who has disrespected me and someone who engaged with others who have disrespected me to the lowest point of my life, going so far as to say the worst point of depression (yes, what you're thinking). we had one more major fight and again he offered no compensation and told me to deal with it until i had a full breakdown in the car begging him to do something, anything so much as to TELL me when they hang out (because he's hidden this from me too).

now, whenever he brings up hanging out with her or mentioning her name i honestly just get dry and upset with him. i hate her guts. i don't care.

valid or not valid? how would you feel in my position.
