To me it seems like it would be good for you to communicate with her about all the things that you're talking to us about. Communication in relationships is so important but unfortunately at the early stages, communication is kind of fuzzy since you're still sort of playing games right? But ultimately you want to be with someone who knows you well and someone you can feel safe to share all these feelings with. I think if you tell her about this stuff you'll find some peace and also probably start to find out whether or not this relationship has longevity. She'll be able to tell you what's actually going on, for better or for worse, but at least you won't have to always be guessing and doubting.
