I’m sorry, what I did was remember the good thing that happened between us, but that didn’t help so I moved on, he was my friend since 7th grade so it was kind of hard, especially the way he ended it. But now I love someone else and I’m happy. But it can be hard with older people since you’ve had more experience with it. So if it helps listen to music that you would not normally like and try not to think about that person, idk if what I just said will help you, but it helped me. Good Luck
