Hello First of all I would like to mention that sometimes you don't have control over the situations and what others do but what matters is how you cope with it. What had happened can't be changed and there is no use of carrying its burden with you. If possible have a discussion with her (you can involve a common friend who can arrange it), and try to sort out the matter that you are sorry for what happened and we should now move forward. If she doesn't agree close this chapter. Focus on your life goals and give 1 hr daily for your hobbies.
