Consider the following: while many people see postdocs similar to PHDs there is a simple difference: you are paid 100% to work for your employer. It's nice of you manage to get research done in the right direction, but not necessary (unless you have some independent funding/sholarship which allows you to do what you want). (If you dont manage to recover you work relationship, your friendship will also turn sour. It's better to try to recover the work relationship and see if she accepts the following and you can be still be friends).

Points to explain to her (you can do this in a friendly way like: "Sorry, but i have to protect the interests of this group and myself. And I would like to help you in achieving better, for which collaboration is necessary".):

• An interesting aspect is that once she puts your group as an affiliation on the paper, you are able to call the journal one the article is published and most likely cause a retraction by saying "this research was not approved and checked by our group, and we are not affiliated with it" (which seems to me a perfectly true statement). Maybe in the end it goes trough ater a few iterations, but the timing could be a problem for a postdoc.

• If she publishes without affiliation, you can sue her for fraud if she worked during the hours you paid for or used material provided by your group (and you can cause a retraction)

• Explain to her that she will get no resources if she does not comply.

• Explain to her that you can not give her a good reference under these circumstances.

• On her own, she seems not to be super-productive either. She is there 12 months and you did not mention that she is visibly involved with any progressing research. Explain to her that this probably would not end well for her anyway.

• Asking her how she feels and that you have the impression that she does not react to some pressure in the way which would be best for her- point out to her to seek counseling. (I had a colleague suffering from a psychological problem with very similar symptoms). If she agrees, set a timescale after which you revisit the topic.
