you know, maybe he had a reason , maybe he didn't but in the end it doesn't really matter , the way he distanced himself from you shows that he doesn't want you , not that there is something wrong with you (or maybe is ,idk you) but don't be to hard on yourself , try to relax and heal , focus on you and after some time find another one (sorry if I look like I don't have a heart , I'm just trying to be as objective as I could , you must be having a hard time)

So sorry...
