My ex keeps reaching out citing she needs help, even though I made clear I don’t want to be friends.

I am (22M) my ex-gf is (21F). Our relationship was 4 months. My ex broke up 1 month ago with me, which was brutal. She said I don’t care for her and I dont put any effort in the relationship. Just after the breakup almost everyday she tries to reach out for some or other thing. Sometimes it’s about my health, sometimes my study, sometimes she needs help with something. Recently she said she need to see a therapist so she wanted me to find one for her(Yes she has mental issue, I am not sure which one). I suggested a therapist to her. To sum up She badly want to be my friend after I have made clear many times that we cannot be frinds, the only thing possible between us is a romantic relationship. I say this because we used to have sex everyweek, sometimes everyday. We both were virgin before this relationship. We both hit a week after we met. I honestly believe than I can’t be demoted to friend, I can’t be with her without romantic relationship with her. I have tried many things: I cut her off for a week. (Blocked) She figured out a way to reach out and become emotional. I refused to help and ”abandoned” her, in her words. I always bring sexual stuff with her, try to flirt as much as possible. But she keeps saying she will never be my gf again. Man, She keeps calling me everyday, I am tired of her bullshit. I don’t want to waste more of my time on her. We are under a lockdown so can’t meet physically with her until November. Please suggest a solution, I am in so much agony.

TLDR: Ex keeps reaching out everyday but do not want a relationship with me.
