The Situation
It ended, and the explanation given doesn't fully add up — something vague about "it's not working" or "I need something different," with no real specifics attached. No blowup fight, no obvious betrayal, nothing to point to as the cause. Just an ending with a reason-shaped hole where the actual reason should be.
Breakups without a clear cause are often the result of something that built slowly over a long time — small disappointments, unmet needs, or growing distance that never got named out loud until it reached a breaking point. By the time it's said, it can feel sudden to you and long overdue to her, because she'd been sitting with it far longer than the conversation suggested.
You may never get the full explanation, and chasing one from her at this point usually does more harm to you than good. Some answers only become clear with distance and reflection on your own, not from her giving you a better one.
Real talk — 'it's not working' from someone who's been building up to it for months isn't vague to her, it's just vague to you because you weren't in the room for the part where it built. Don't spiral trying to reverse-engineer a paragraph out of a sentence.
There's more nuance in your specific situation than this covers — bring it to the Council.
