If the relationship ended on good ground, there's a chance you can get her back. If it didn’t end well, it’s hard to determine how its going to work out between you. Try and talk to her and remind her of the good times you had together. Change yourself for the better and when you do, tell her that you changed for her and for the life you dream of having with her again. Be kind to her and listen to what she has to say about getting back together. Hopefully everything works out for the best and you get back with her.
