Sandi and Puppy gave you really good advice. She WANTS you to tell her to stop, she NEEDS you to help her stop......I agree with Sandi, you need to ask her what made her come back, and then go from there.
I see what you are saying about the drama about coming back at night. The affair was fantasy, coming back in the middle of the night at the doorstoop is kind of fantasy as well. Let her have the warm thoughts of your reaction to her return, but also now is the time to ask for her to do these things. Don't wait.
