The Situation
She said it plainly enough — "I'm not happy" — and then stopped there. Every attempt to get more out of it hits the same wall: "I don't know," "it's not one thing," "I just feel off." No incident to point to, no specific complaint to fix. Just an admission with the reasons withheld, which is its own kind of hard to sit with.
This usually isn't evasiveness for its own sake — it's more often that she genuinely hasn't finished sorting it out herself. Unhappiness that builds slowly, from a hundred small things instead of one big one, is hard to summarize even for the person feeling it. Pushing for a specific answer she doesn't have yet tends to produce a rushed, partial one that satisfies neither of you.
Resist the urge to solve something you can't see the shape of yet. Ask smaller, easier questions instead of the big one — what part of a normal week feels hardest right now, what she wishes was different day to day. Specific questions get further than 'what's wrong' ever does.
Notice whether this is a first conversation or the fifth version of the same one. If you've had this exact exchange before without it moving anywhere, the pattern itself is the problem — not the missing reason. That's worth naming directly.
The specifics of your situation change what actually helps here.
