What to do after this breakup...

Ill try to make this as clear and brief as possible.

My GF and I finally broke up after a 5 month relationship and 2 weeks of a "breakup time-lets think about it" time. We are 19 and 18 years old respectively. I was her 10th boyfriend and she was only my second. You can see my previous posts to see what detonated the problem.

After having some incompatibility-tolerance issues, she stated that she was still confused about her feelings towards me. I love her, and she (as well as me) is sure of it. She loved me, but now she is unsure. Emotionally she is pretty much unstable and confused. Very social, she states that she is "unable to be alone" and seeks company quickly.

Although this relationship was a breakthrough (emotionally and sexually) for her, I know that she really cares for me, because she could easily have continued the game, but prefered to be honest with me, something I liked. It was a tough decision for her, one taken from the head and not the heart. In the end, we left in tears after a passionate kiss. I told her that if she regretted the breakup, I would be glad to try it again. She said she hoped that happened, but that first she wanted to know by herself.

I perfectly understand that. After reading some work from Erich Fromm, you cant have loneliness issues and seek company, cause it wont work. But, the point is: if I want to return with her, but also want to get over it, what should I do?

She told me that we could still see each other, but I replied that I couldnt do that, cause I will keep on dreaming. She is a very strong person, but she seeks me through instant and text messages as well. Should I ignore her? Block her? Try to have some "we are friends" approach? Speak clearly and tell her that I'm sad?

Breakup was on sunday, I really want to go over it, but Im still in love.
