Getting dumped

So my boyfriend of 1 year recently dumped me after telling me he didnt love me anymore over facetime, and I don't know how to get over it😁I see him almost everyday at school(in my AS classes) and I feel like bursting into tears whenever I see him. I have to work with him in a group in one of my subjects and I don't know how im going to do it😪 how do you get over breakups and do you have any tips for moving on???
