EDIT: In my own viewing, when a woman tells you she's confused, it's essentially an excuse to make another excuse, and excuse after excuse to desensitize what they did wrong. When a woman is confused, it always means she did something on her end. Therefore, the tactic of desensitization comes into play.
They use this tactic to create distance and time, 'time heals all', or so they believe. Then they come back all nice and sweet.
It also means, they're low-key admitting they were thinking ahead a.k playing games. These games are akin to white lies, and like snow add up over time and collapse on their selves like an avalanche. Stay silent but watch her, and when you see a thread in this tapestry she has constructed, pull on it, and it all un-ravels.
She will get defensive, and remember that by defensive I mean the simp mechanism. "Oh, she's crying, that was wrong of me!" No it wasn't. You did right. She did wrong. Keep that thought in your mind when that happens.
