How to resist going back to a relationship that you know isnt working?

r/

I f23 dated this guy m25 for around 2 months. He’s really kind and sweet but i thought it over and over and i just figured out that he has way too many other issues to have a good relationship with him and i’ve already seen enough of those. Without talking about the fact that it’s affecting my overall attraction to him.

I finally found the courage to end it and i had an honest conversation with him after waking up to him having yet another issue. But i dont know, despite knowing it was the right thing i kind of feel bad and sad, and i dont hate him. Doesn’t help that he’s not a bad person, but he’s too insecure and anxiously attached and i got tired of acting like his therapist. Or walking around eggshells to not upset him. He likes me way too much tho and he told me that maybe my decision was a mistake and that i should think about it again.

I know for a fact that i’ll miss having someone caring about me that much and filling my time and thoughts. How do i shake off the feeling. And not come back again? I need someone to shake me off lol
TLDR: i broke up with him because of his insecurities and cliginess along with many other things but i know he liked me a lot. How to remind myself to not try again
