Getting over a breakup

me and my (ex) boyfriend weren’t good for awhile and we took a break, and we broke up yesterday. it was mutual and we both want to be friends, we just weren’t meant to be anything more than that. and i thought i’d be fine, happy,

and relieved, and i relieved but i’m upset. i think bc i wanted it to work so bad but it didn’t? anyways i’m not as okay as i thought i’d be. any advice on how to get over a break up? (in case you couldn’t tell this was my first relationship lol)
