I've been broken up with 2 weeks ago after a 2-week relationship, it maybe a short period, but it was devastating for me since it's the first time someone take the initiative to break up with me, never felt that before. I practically used the same approach as you, but i wonder if i'll be over my ex someday. I feel like i haven't enjoyed his company enough while in the relationship. In fact, when i see guys that are way hotter than him, i won't feel any attraction for them, and i would bring all the good things about him even if i know that he has many vices i wasn't happy about. I fear that all of this thoughts stops me from getting over him..
