Mesed Up Break Up

I had this boyfriend for 2 yrs n everything was great although there were lies,cheating,backstabbing,using,manipulat ed n everything else...we talked every night for hours n had interesting conversations n i thought he really cared but less then a week ago he stopped calling me n texting me n everything he just shut me out of his life...n i wasn't sure y until his friend wrote me n said that he was with her friend n they were together..i didn't believe it so i text n called him but he didn't respond so i just figured after a couple days that he didn't want anything 2 do with me so i basically told every 1 it was over..n i thought i was ok with it but then when i actually talked 2 his g.f n she said they were together n stuff i felt sick i tried 2 tell her about him but shes FAT n has low self esteem so it didn't help ..n so i had her call him n tell him that i was gonna call n he needed 2 tell me if it was over or not..(i expected an explanation) but i didn't get 1 alls i got was a its over n a click..n i cried n cried n cried..n now im not sure what to do...any ideas..
