My Ex girlfriend text me a happy birthday text last week after 8 months with no contact.we decided to call it a day in sept last year as she was hot and cold with me and I just could not take it any more as it was just messing with my head allthe time!i said I think its best we call it a day andshe said as much as this gonna hurt me I think you are right,i will always love you and will take it to my grave.i as anybody else would be asking why the hot and cold...one question poped up!she found some 1 else,i asked her if it was and she said no it wasent.that was sept last year and in December I found out she was engaged and I just broke, but at least got my answer to move on etc now 8 months down the line I get a birthday text!why!? I Haven't replyed to it and deleted the text!
