my ex

so yesterday night my friends dared me to log into my ex’s snapchat and see if he changed his password it worked and after it logged me out and he logged back into his account proceeded to call me a crazy hoe and blocked me on snapchat. my friends didnt tell him to stop and never told him that it was their fault that i logged in and just laughed at me. i really dont know who i can cal my friends anymore if they laugh at me and rub in the fact that im no longer with my ex. i really miss him and he meant so much to me. any advice on how i can get over my ex so im not so sore over the subject of him?
