Whether you stop talking to her or not, if you're not getting back together then in time you will forget about her. It will be easier if you stop talking but if you want to try and 'stay friends' then you just gotta wait it out. Whatever you do, do not fuck her again in the hopes that you'll get back together. If you were going to get back together, she wouldn't have waited 2 months.
Breaking up is awful but time really does heal. They say it takes half the length of the relationship to truely get over someone if they broke it off and you still wanted in = 6 months for you. One day you'll realise how much better off you are without her. The other advice is good too, fuck some other girls, hang out with your guy friends, hit the gym.
