update: she cheated on me

basically she went out with her new college friends and she got drunk and she kissed 2 girls on the lips even though ive made it extremely clear im not okay with that. its extremely disrespectful for me and it's something I'll never excuse. basically she drunk voice messaged me saying "i don't want to tell you this but i have to" and the she kissed two girls. after she got back i asked her once more if it's true and she said yes. then i told her I'm done im not going to entertain this anymore and blocked her. her excuse for doing this was "you only told me it'll make you sad but you didn't tell me you would break up so i did it" 🫩

and then later she texted me on another platform saying that she loves me but she loves herself more.

feeling devastated but that's just how life goes. anyways how do i move on from this as quickly as i can? ive never been this hurt before.

please give me advice on how to not think about this over and over again
