After about a relationshp of 2 years we broke up becoz of some problem and i was so rude and haterd towards her on my last phone call that she was gone .. I love her and she loves me but we separated on 10th dec 2010 till we haven't talkd to each other i msgd her but she didn't replied .. Even after 6 months of break up she is in my mind i love her madly but she dnt want those days back because of my bad attitude .. What should i do ? Will she ever be bak ? Her family dnt want her to be back to me . . Should i keep the hope ? I am dying frm inside ,nobdy is there to discus so i am using yahoo answers
