Conversing is fine. Letting her talk/vent about her day is good stuff.
Just remember not to push her or pressure her, let her share what she wants. You are to be the safe place for her to land.
Watch out for relationship talks - even ones she brings up - especially those. Until she is demonstrating consistency in her behaviour towards you, kids, sleeping arrangements, life, etc... she isn’t ready to delve into that. For the time being R talks are more of a trap and used to further a crisis person’s justifications for their actions.
If you pay attention and let her talk she will say lots. As she feels more and more secure she will let slip more and more. Stay non judgement - a tough task, depending on what may be revealed.
Remember - do more of what works and less of what doesn’t.
You’ve mentioned that as you’ve detached more she is opening up more. Good stuff.
Keep moving forward and see what happens. I am sure more will be revealed in time. Dig for patience and do your inner work.
Inner work. That’s the successful path. Be the best man you will be.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
