Model Help with R line

I struggle coming up with R lines sometimes.  Here’s my Model:

C: My husband said, “I am going to quit our biz and it’s too hard for me.”
T: I don’t want to hear it
F: Annoyed
A: Walked out of the room, avoiding talking to him, giving him cold shoulders, ruminating the unpleasant event in my mind,
R: I kept listening to his complaints in my mind?

I’m not sure about the R line. Will you please help me come up with some R line?

Are there some general tips about coming up with the R line such as some common words or phrases we can use to help generate it?  Is it always a reflection of the T line?  How can I double check if my R line is correct?
