How can i get him back? 10 points?

first i would stop drinking because it just causes problems. i think you could call him or text him to meet some where to have coffee or have lunch and talk as friends. just ask him how he has been and take it very slow. try not to act interested in him or seem desperate. the first time you shouldn't expect him to like you Again you have to give him time, also at the end say "we should do this Again sometime" so you have any other chance. and also try to look your best but not formal try i new look it could tell him you have changed and is looking to start over. if he has no romantic feeling for you then, he might need more time, make sure you don't seem like you have romantic feelings for him. you could even say you had a boyfriend . he could get jealous and try to make a move or he could see that you've moved on from him and want you back. guys want what they cant have.
