爱只剩下无奈我不愿再去猜
[ài zhĭ shèng xià wú nài wŏ bù yuàn zài qù cāi]
The person acknowledges that love now seems futile, and there's an unwillingness to continue second-guessing and overthinking situations which likely relate back to failed attempts at love. There might be a feeling of tired resignation regarding feelings or interactions related to romantic matters.
