how do i let go of someone while having a trauma bond with them

idk how to let go of him, im tired of feeling the way i do whenever he leaves me then js walks back into my life. i wanna let go so bad but idk how to. does anyone have any tips. esp on how to make good connections with people so i can move on. i find it so hard to make connections bc i always feel like its cheating even when im single. he broke up with me again. abt 2 hours ago. n i haven’t stopped crying over it.
