I am very confused. Will someone help me?

My ex girlfriend broke up with me harshly on my birthday during January 2011. It was very hard for me because I loved her a lot and I've been depressed since then. Everything was hard for me to do because she was always on my mind and I missed her so much and I loved her so much and she did not feel the same. She was going out having fun and clubbing. We used to live together but had to part ways because she joined the military. She broke up with me during that time she was away because she said that she just lost love for me. She said the feelings just disappeared. Now she will be stationed at a base 2 hours from me and she told me that she still wants to hang out with me. This is where I am lost. I don't want to get hurt by her again and I don't want to fall in love with her again. Ive been thinking about texting her telling her that I don't want to see her ever again and I don't want to talk to her ever again or hear from her or about her. I don't want anything to do with her because she caused me so much pain. But something in me is stopping me from texting her that I don't want to see her ever again. I have a very tiny little feeling that I am going to regret it. So basically I think I don't want to fall in love with her again and I think I just don't want anything to do with her because I am afraid of getting hurt by her again but then something is stopping me from telling her never to contact me again. What should I do? Should I just hang out with her and see what happens or should I just avoid her to save myself from a possible heart break again?
