At least your W moved back in after filing for D. I was hoping mine would not even file once she saw what it would do to us financially. Her folks will help her out with money and she is happy to take it so that did not work. The reality of it is that I did not want her to stay for financial reasons anyways. My wife has cut off all contact and is ready to move on with her OM.
I wish I knew what to tell you. I understand you care for her but you also have to look out for yourself. She is divorcing you either way. Giving her money is not going to change that. Just don't make the decision for spiteful reasons. Make the ethical and moral choice when it comes to the money.
Also, the remark about convictions to you marriage was not a good idea. No need to stir the pot.
