久伴后的孤独
[jiŭ bàn hòu de gū dú]
The phrase translates into 'Loneliness Following Long-Time Companionship,' conveying deep emotion regarding the loss or transition of long-standing relationships, marriages, etc., where companionship once felt fulfilling and safe suddenly fades, revealing loneliness. Users could express pain after separation, whether voluntary or forced (due to circumstances beyond control), while grappling emotionally post such significant relationship upheavals.
