i want my ex gf back

My girlfriend and I broke up 3 months ago . We had something special , we really did care about each other no matter what . We did have a lot of quarrels mostly because I was annoying. I've never scolded her nor went against her cuz I respected her and I really loved her . On 7th month she sent me a very sweet text saying she really loves me and wants to be with me forever and all . The very next day after monthsary she broke up with me.she didn't talk to me the entire day but she talked to some guy on twitter instead . And at night she broke up with me .. All she said at first was that she wants me to study so yeah . Which is crap . Later on she said not now ....I'll decide again after exams . I was REALLY REALLY EMO AND ANNOYING after the breakup . I kept asking her to comeback and all . She was irritated . To be honest I've not done anything that would cuz the breakup . Okay to cut it short after a few days after the realtor she went in a relationship with the guy on twitter she was talking to .. They were together for about a month or two and broke up .. And I was hurt and all that . She herself scolded me a lot said I'm annoying and all that . And told me to Fk off . She doesn't want me back . Well now I really do want her back . Shes single now ... I just don't tell her anymore that I love her cuz she told me there's no use saying it . She doesn't care . Well now I just wanna know how can I get the one I love back? I really do love her even after she insulted me and dated someone else . She does text me at times . Help me please ?
