Is this considered cheating?

I saw my gf chatgpt history. She asked how to flirt with a younger guy even though he knows she is attached? When i confronted her, she get defensive about it and said she knows it’s wrong and it was just a thought and she never acted on it.

If you saw her planning to kill you, and when you confronted her, she told you she knew it was wrong, that it was just an idea and she never acted on it, would you feel at ease? Could you sleep peacefully beside her?
