So as pathetic as it sounds, after a year I am STILL not over my ex. He broke up with me last September completely out of the blue (and that's not just me being naive and avoiding signs it was genuinely out of no where) and since then I've been trying to piece myself back together again but still don't feel like the old me.
We got on so well and had such an open relationship,we could tell each other anything and he genuinely made me so happy, although I will admit the sex wasn't great!
Anyway he broke up with me saying he didn't have the time in his life for a girlfriend and couldn't give me what i'd want from the relationship and went on to do the whole we'l stay friends speal adding that he really didn't want things to turn awkward. So we continued to text and talk most days until eventually that fizzled out to nothing.
Since then I havn't been seeing anyone and the most action iv got is a cheeky shift here and there.He's single too as far as i can tell. I do see him the odd time as we both commute into the city during the week but its as if we're strangers. A half smile is the best you'd get out of him and if not it's dodging carriages or completely ignoring me, however despite this I still find myself looking around to see if i can see him.
Seriously what is wrong with me ?? I know i should be well over him by now but he is constantly in my head. Although i know it will never happen i find myself wondering if we'l ever get back together in the future or if he ever thinks about me the way I do of him. Complete nonsense I know but i cant help it and it's driving me crazy!! I just want to move on and carry on with my life but i cant , somethings holding me back and i don't know what it is. Even worse the relationship only lasted 5 months so i really have no excuses at all for acting like this!!
Please please please give me any suggestions you have or literally any comments on the situation whether good,,bad or indifferent. I really need to see this through other peoples eyes so any input at all would be much appreciated.
Thanks

(Also just to add he was the one who chased me and kept at me about getting into a relationship. The one talking about the future when we we're together as if nothing was wrong which I think is why I'm finding this so difficult , he never mentioned anything about being too busy to see me or anything like that. )
