Just to echo what Rive and LT have said, the ending via text is hugely problematic. As someone whose therapist ended in a similar way (although we had a variety of other issues too), I would not work with someone who had shown me such disregard and lacked understanding about professional standards. Ending in such a way is harmful.

You say it's a no-brainer to go back to her and other posters have said it makes sense so maybe I missing something, but it's not clear to me what draws you back. You mention some practical considerations, but beyond that, what does work with her offer you?
