(Ex)-Boyfriend? --- Long question.?

So I was best friends for my boyfriend for 7 months, now were dating and have been for two weeks, he breaks up with me every other day. I had my first kiss with him, and other things. I love him...So much. Every since the day i met him i LOVED him. . . Then he decided to break up with me for the 3rd time this week....And he likes my BEST FRIEND, and their talking. everyone knows im madly in love with him. . . What do i do? Im so heartbroken. . . left out... jealous. Just wanting to die. I know he will probably come back for me but it wont feel right. I cant get over him either. I miss him so much already. His locker is right besides mine and i have to see him EVERYDAY. He said one reason why he dumps me is because i put myself down (calling my self stuff) I simply said " I only talk bad about myself because you tell me how you like other girls." He said "Whatever Bye" And hasnt talked to me since. . . Does he hate me? And the GIRLS he talks about are my BESTFRIENDS! Do i deserve this...? And how can i get him back? Please anserw....:/
