Women, how do you survive breakup with a love-bomber?

So I (22f) was with this guy (23m). He love bombed me a lot in the few initial months

He-

Promised me the world

Did everything for me

Made me show love in both actions and words

Made me feel like the absolute goddess

Told me I am the love of his life and he never loved anyone before or after me

We got separated and he yearned for those 3 years for me .

Yet he broke up and did everything opposite of the love bombing . Now idk which side of his is real.

This rude one after and during the breakup or the one before it.

Mind you I didn't do anything wrong he always decided to leave me whenever emotionally difficult or overwhelming situations arrive in our relationship

I have been abandoned by him 3 times now. I am not ever going to take him back

My question is just when your mind is all foggy with both the sides

One where he loved you like a goddess, absolutely perfect love , like movies and fairytales

And then on the other side these men always show after love bombing you for months and then suddenly they decide they don't want you and the relationship anymore .

How do I get this out of my mind and him out of my life completely so he never ever uses that soft spot again to manipulate me and put me at my worst.
