history: I didn't tell my friend when her boyfriend hit on me. I felt very bad and wrong for that, even though I turned him down, of course.
current: I didn't tell my friend when her boyfriend hit on me. She was in a bad spot and needed him for financial support, and that's why I didn't tell her. But, I still felt so bad about it.
next: I can empathize with you there.  Do you think there might be another way to let her know?
