That is waaaaay too much analyzing. You are obsessing. That's not healthy for you, and also, you have seen already that backing off and letting her have space had a positive effect for you. So try to get your focus back on you. One way to help yourself do that is to not discuss with other people things like whether or not it's strange that she gave you her phone number.
Sit back, let her reach out to you, and show a positive mental attitude that you will miss her but will be just FINE without her and she can have all the space she needs to figure out what she needs.
