i want my ex back..

so i dated this guy for about 1 year and this was my most meaningful relationship i’ve ever been in. he was my first time with everything yes we were intimate. He was the only person i trusted and we got really attached we couldn’t leave eachother. he did everything for me and i didn’t appreciate it enough for example i’d ask for help with mental illness and he’d help me but if push him away making him anxious. i never gave him freedom because of my trust issues but apologize after. recently a month ago he broke up with me because he was tired of it. the connection was so strong but the relationship wasn’t. a few days after the break up we chatted still telling eachother we still love eachother but we can’t force this process. even then i still begged him and drained the shit out of him. big mistake. if lead him to moving on and finding another girl. he told me he wasn’t going anywhere and he could still facetime and text but i ruined it for us. i hope to still have a chance but j need advice on how to get that back. i love him so much and i just need to know ways on how to fix what i did and guidance. i don’t want someone to tell me to just move on but just if you know how i can redo the past and hopefully get another chance please reach out. thank you
