She told you that she was feeling self-conscious, which was very weird, because normally such things are not shared with somebody one is yet to meet in person. So she is very weird. Rejoice that you have not invested MORE of your time and energy into this could-be relationship. Do not try to think about what she should or should not have done - a person who keeps postponing dinner dates talking about feeling self-conscious is too weird for your logical analysis. Just drop this case, and if she ever contacts you on her own, tread very carefully if at all.
