<human>: My exgirlfriend and I broke up around 3 years ago. We have had a love/hate friendship since. We both go to different colleges, but we hung out over christmas break. Over that time we started talking about how things are between us in the current state of things. We both made it clear that we still care very much for each other.

After christmas break there was a sort of afterglow, we would text all day and phone calls at night. I was happy that this was happening. There were some times she called while drunk talking about how much she wants to have sex with me, and she brought up how badly I miss her. 

Now it's late February, things have changed. She isn't as talkative, actually almost not at all. I asked her the other night if she was mad at me about something, she claims she isn't. She did admit that she was distancing herself from me. She claims she doesn't know why. She's admitted that she's terrified but won't talk about it any further with me. 

In the past I was the one who broke up with her. I'm the one who left her to go after "fun" girls. This was high school though. I feel like this is a problem now. She knows my personality. I'm ambitious. She thinks she won't ever be enough or that I'll lose interest in her. I know deep down it's these same sentiments coming back to surface now that she and I are (or were) on good terms. What should I do? I hate waiting. It kills me to have her ignore me. Is she worth it? Yes. It is unfair though that I am being emotionally neglected. I've always been some what self obsessed, so I enjoy people telling me how they care for me. Especially a girl I love. So what do I need to do? It's all extremely frustrating.

Can you summarize the given text in a few sentences?
<bot>: Everything was back to the way it used to be but now she is showing apprehension. She is scared of me hurting her I think. What do I need to do? Stay? Go?
