How do I get him back

it depends. First you have to examine the reason that you broke up and decide if it is healthy for you to even get back together. Then if you are sure you are thinking logically not just emotionally then I suggest you are just honest and sit down with him and tell him that you want to get back with him, why you dont want to be without him and what you can do to make it better this time

it depends on how long you guys were together if it was a serious realationship then this is what you can do it might sound wierd but trust me on this one it will work don’t call him when you are at school or watevr walk rite past him pretend you don’t even see him I know its gonna be hard but try to start talking to his friends and see if he been talking about you if so you have a chance

if it wansnt a serious realtionship then srry but I have no advice for this part gud luck
