I need some honest relationship advice

I was with this girl for 3 years talking and dating together, it was long distance but we always made it work. We broke up around July for the reason of the distance was getting to hard for her to handle which I understand. Every time she would leave me she would be crying her eyes out. So it has nothing to do with her not loving me anymore.

So now we are here and we talk off and on..she dumped her ex for me bc she still loved me they only dated for about 3 weeks...she keeps saying she doesn't want a relationship right now which I understand but she tells me she loves me and we talk about a future together all the time...

Every time me and her start to get along great and are happy with each other something happens and she freaks out and changes her mind about everything.

For example I was going to goto the Egg Bowl win her this weekend she begged me to come up so we could be together the overnight she changed her mind and now we aren't even talking again...

I know all women are insane but can someone help me out here this biotch has got me confused as hell
