Well, I talked to my sister's husband again and told him some more. My sister keeps lying to his face. I went over to talk to my sister today. I told her I talked with her husband and told him some things. I was happy that it went well. She didn't get mad. But from here on out, I'm staying out of it.
I did try, however, talking her into staying with her husband. I said she'll regret it someday.
