It's nice that she acknowledged your feelings via text. As someone who struggled with NGS, I know I would have read those texts and wanted them to mean at some level that my X was finally understanding me. I don't mean I would have lapped them up, but reading them through the NGS lens I would have felt a flicker of connection.
I can't say whether or not she actually cares how you feel, but at least be aware about how much *you* care about how much *she* cares. The less you care, the easier it will be to detach, to be confident in yourself, to set and enforce appropriate boundaries, and to avoid falling into NGS tendencies (which your W likely expects you to do).
I agree with the others that your boundaries will be tested. If you've ever seen "Jurassic Park", I like to think of my X as one of those velociraptors constantly throwing themselves into the electrified fence, just to test that it is still juiced. Boundaries require consistency over time. Kids do the same thing.
