Lay what out?
You are not supposed to be talking to her about your relationship.
Do not rescue her financially. You should not be subsidizing her love nest. Let her feel the discomfort and figure it out herself.
Memorize the following:
1. "Yeah, I can see how difficult this has become."
2. "This isn't working for me."
3. "No"
Repeat as needed to any of her problems or questions..
