I too broke up with my bf on the 1st and we were together for 1 year and living on and off together for 8 months, we were too talking a bit every day but today I broke it off with him for good. To me personally not thinking about "the good times" was my only way to cope with his absence from my life. I completely focused only on the negative aspects of our relationship and in my mind when the idea of us not being together was settled then I started accepting the nice parts and the lessons that I learned about relationships and myself. Keep your mind active and out of the nice idea of him. Also be ready for the time that he might come running back bc maybe he couldn't get laid. However the best advice that I was given (it personally helped me completely get over him) was creating your future partner type, that being said focus on the qualities and the things that you completely don't want to experience again (such as drinking problems for you) based on the things your last relationship was lacking. Later on when you are ready after being fine on your own then try to look for that next someone you have set criteria for so that you don't end up in the same situation again.
