Just got dumped after 6 months 😔

Ellaa
This was my first proper relationship, he's just got back from schoolies 3 days ago to say he's lost interest and ""he didn't miss me on schoolies""....
Can people tell me how they got over there ex's coz I'm having a very hard time, I've chucked or hidden all the things hes given me over this time. He's also blocked me on all social media so I guess that's helpful too but I need advice please 😔😭😢💔
