When my ex finished me, she said she didnt want to be friends because she thought i'd get the wrong idea. So i did 2 weeks of no contact and she called, because she missed me and wanted to be with me, but still she told me not to get the wrong idea. I went to see her, and things were different, she treated me like i was her boyfriend etc.

If you are friends, you have the chance to make it solid. I would give it a bit more time until you become friends.
