No real change here. Also, sometimes there can be several false starts to reconciliation. I would say just continue to do what you are doing -- focusing on you, your son, and as Steve says to stay above the crazy. Keep being that lighthouse and keep standing tall. Keep being a strong father and the man only a fool would leave. That will continue to improve your confidence during a D.
She may go back and forth, throw out hooks, and she may change her mind and/or genuinely not even know what she wants for a long while. You can't control that. But the thing is, there may come a day -- in a few years or maybe just a few months -- where you both decide to give this another try. This even happens after D when the dust has settled. Sometimes after D, people feel less anxious about the unknown and can more clearly reflect on what they have lost.
She is still paying attention to you, clearly. You want to know that you handled yourself well -- for your family, your son, and mostly for you. Don't let your feelings about her and a D compromise your integrity. That is the hard part when someone jerks us around! Keep doing your thing -- stay quiet with her, but keep standing tall for you and your son. You got this.
