Let's say a friend of mine has just gotten divorced. It was his ex-wife's decision. So now he has moved out while his ex-wife is staying in the house with their children.
If I have just learned all that, could I say this: "How could she just leave you, after all those years?"? Would "leave" be the most natural word to use even though the consequence of her decision is that he's the one who had to move out/leave while she's staying in the house with their children? Or would you steer out of it and phrase the question differently?
