How do you get over someone you never dated?

I posted on here last week asking for advice on how to cut a guy off. I'd been talking to him since April 2019 and he still claimed he wasn't ready for a relationship all now. I cut him off on Friday and had been managing to hold up until he sent me this message this morning.

I find it strange that he can claim to feel that way and still not be ready. I broke down when he sent me that. How can I get over him? I told him I just need some time and I would appreciate if he respected it. How do I get over him?? I like him SOOOOO much. 😭😭😭😭
