Re: I might have scared her
The number close did seem a bit awkward. But I don't think this killed you. It's way too minor to just completely turn her off from you. There has to be another reason. Something that you have or have not done up to this point or something that you have no control over (such as an ex bf). I wouldn't beat yourself up too much over this. AFCs can be far more aggressive and amateurish with trying to get the phone number. Simply do a freezeout and reinitiate in about a week.
