should i end it on his birthday?

okay so this guy i’ve been seeing for a few months now, he’s really not the best guy. none of my friends like him. my mom told me to get a restraining order. he’s a narcissist. we aren’t actually together anymore. but we still talk/see each other sometimes, still have sex. well recently i cut off sex because i want him completely out of my life and i won’t be able to do that if im sleeping with him. i typed out the message to send and block him. but his birthday is tomorrow. i tend to stay because im an idiot. im a people pleaser and he always guilt trips me. makes me feel like a bad person and plays victim. so then i feel obligated to still fuck with him. but i’m at a point im so tired of him. he’s been “down” the whole time we’ve known each other. it’s like he never has a good day. i can’t rely on him. he doesn’t do anything for me. he gives me the ick. i’m completely turned off by him. but for some reason i just don’t want to hurt him. my friends say to either ghost him and block or send the message and block, on his birthday.

but idk what to do.
