I am proud of you for wanting to get over her, but do you really want to? It seems that maybe you're unsure because you need to ask others.
Ask yourself if you love her, and if you want her to be a part of your life, as a friend, or girlfriend.
If no then simply do things for yourself. Do the things that make you happy, and in time you will get over her.
