Most Helpful Girl
Sounds like my ex wouldve wrote this. So let me tell you to let her go. If you have done 'bad things' it will be in mind forever.
I know how it is.. you think you have changed and when you think of being with her, when you miss her. You think it will just go back to the beautiful beginnings you once had.
What you can do it you really want her back is show her that you have actually changed. Pay attention to the little details. Gain her trust, show her you love her. Be the guy she first fell in love with. Without the past, without the baf
If YOU want to be happy move on.
