What should I do . . . I love her

dear friends hello;

I’ve been in a relationship with my girlfriend about 1 year and a half, she 's a student in other city in my country but it’s close ( 3hrs by taking bus) now we broke up… I broke her heart and tell her stupid thing when I was nervous … and now I want her back yesterday I start no contact period … I wanna to know while she’s student in other city
How can I attract her after NC period ?!

thank u !
