Hey Brian, great with all the contact. I think it is her further reaching out to you.
However, I will also say that the validating is good. The over emphasizing that she is sharing with you, forget it.
I think it is more important that you simply listen. I would stop thanking her and maybe just start acting like it is normal. She wants to have a comfortable convo with you and not have it always have to mean so much.
Try and remember to act like she is your best friend right now. Just talk to her,just listen, journal how happy it makes you rather than telling her that so much. She is opening up to test the communication and comfort levels. Just be her friend buddy, that friendship will lead her back home.
