If you really want to move on there is no easy path forward, But there are some things you can do that will help. Although it sounds like your more interested in picking the relationship back up, maybe you dont need to move on just yet. at the same time, i dont know what caused you two to break up, and its important, because theres a number of things he may or may not have done that could warrent treading lightly and carefully.In any case, if you want to move on, its slow and tough, try writing him a letter you wont send, or talking to other people all together to take your mind off of it, that way you can think clearly. Otherwise i wish you luck, whatever you decide, will be difficult.
