"then it will show her that your "changes" are a ploy to win her back..."
This isn't true.
The conversation was based on total honesty between the two of them and that they were both on equal footing. Having an OP complicates matters and is an unfair variable against Snow. He has apologized for his past behavior and has shown his changes. He's put in the effort. She, on the other hand, is seeing another guy behind his back. Not equal.
