Moving on

ok i dated my ex for almost two yrs. we been broken up for two months now. and he already has a new gf. i talked to him to see if there was still a chance, but he was just rally distant and had up this wall like it wasnt even the real him. i ask if every thing he ever felt for me was lost like if he was over it and he said 'yeah it's gone'. he couldnt even look at me the whole time i was talking to and at one point his eyes were watering. he said that he does love this new girl, and that he only cried for 3 days and got over 'it'-us. i understand that i cant keep chasing him and i need to move on. it just hurts so much because i thought that if he saw how much i put myself out there to even approach him that he would have some compassion or at least understand but all he could say was that he was sry to upset me. we were best frineds for the longest and he couldnt even look at me in the face, and now he has a new gf that he already loves. did i miss something? what ever he took to fall out of love with me i need some too, and if he's lying i dnt know why i was always there for him.
