他骗了我整整一个曾经
[tā piàn le wŏ zhĕng zhĕng yī gè céng jīng]
'He Lied to Me Through an Entire Past'. It indicates being lied by someone important in his/her memories for a long period. This may imply the pain and hurt experienced due to betrayal and deceit, and it may be a feeling that is lingering in the mind.
