What would help right now?
You do not need to choose a product mode. Start with the need that feels closest.
Talk it through
Start with whatever is weighing on you. You do not need to know yet whether anything needs to be said.
Set a boundary
Get clear on what needs to change and how to say it without turning the moment into a fight.
Repair after conflict
Find a way back in when the relationship matters and the last conversation did not land well.
Practice the conversation
Try the pressure of the real conversation before you have to be inside it.
Bring them into it
Open a shared space when hearing each other would help more than another round of talking past each other.
Talk about what happened
Come back after the real conversation and work through what changed, what did not, and what you want next.
