Should I leave this friendship?

soo my closest friend and i haven’t been talking because they have just been ignoring me even when i called them to try and ask what’s up. so i have given them time and they just haven’t reached out to me in like a week or two. i don’t know what I've done they always do this when they are angry at me or just don’t wanna talk to me but never for this long. i stopped talking to them properly for a bit because they always cut the phone on my when i’m talking. i’ve managed to control my anger but the last time they did it i was angry because they made me feel like what i was saying was foolish and it was not. i genuinely feel like they despise me and always have because they treat me different than my other friends and do stuff that they would never do to any of our other friends. i have tried reaching out but if they don’t want to talk to me then I don't know what to do but i think this is the end of our friendship.
