my ex boyfriend and i broke up a few months ago. then after a certain amount of seperation we decided to be friends. now its been almost 3 months. we talked last night and i told him that i was crazy about him. he said that he had feelings for me too, and that he wanted to get closer again and take things slow, which is awesome. but then he said that he didnt want to date me again? like in a relationship? i understand that we're leaving for college in 6 months, but i really want him all to myself. (because theres this other girl that likes him, and hes trying to decide if he likes her) if i wait a few weeks and he still doesnt want that, i'll just do no contact and move on. he's just worried about getting into to somethingn too serious, or too stressful since we're leaving, but i know that wouldnt happen. can i prove that to him?
but as of right now, is there any way to almost manipulate him into going out with me? like i said, im not stupid, i wont just wait forever if he truly doesnt want that. but i know that it wouldnt be stressful, and i really want us to give it a shot. we truly care about each other and its not enough to just be friends. he was an amazing boyfriend, and i want that back

how, over the next few weeks, can i get him to think its a good idea? (without being blunt because we agreed to just be chill over the next few weeks and "see what happens")
