她没我坚强所以你走了
[tā méi wŏ jiān qiáng suŏ yĭ nĭ zŏu le]
'She Isn't As Strong As Me So You Left' expresses a sentiment that she isn't as resilient compared to me which might make her unable to meet certain emotional needs, leading the subject (you) to walk away from the situation. This has negative connotations including sadness and resignation.
