i cheated and feel terrible

I (f25) and my now then boyfriend(m23) have broken up two days ago. we been together for almost 2 years. we are long distant at the moment and i just travelled to him so we spent new years together and i just returned home a couple days ago. i did something stupid. i hung out with my ex. he came over and we made dinner together then we went out to a bar that’s close to my house. we didn’t do anything. no sex. no kissing. no touching. but my boyfriend found out and he broke up with me, which is rightfully so. i’m not looking for any sympathy as i know i fucked up and i feel horrible. my boyfriend says he’s done and tired. for context, we have both cheated on each other in the beginning of our relationship, but it’s been a year where we both built trust for each other. then a year passes and i’m the one who cheats.

i know he’s not wrong at all if he doesn’t take me back but is there a chance? we still have been in contact for these past few days and still share each others location but he says he’s single and doesn’t want to be with me anymore. a part of me is being delusional and thinking he’s only saying this because he’s mad and hurt about me cheating. but maybe he just has more self respect and won’t tolerate me.

what can i do to get him back? give him time? but what else? maybe i’ve broken all the trust we built together. i don’t know why i cheated. i was just feeling lonely and unloved by him and i knew my ex was available for me that night. i feel literallyyy stupid and can’t handle myself right now. please give me advice
