毁我爱她纯属眼瞎
[huĭ wŏ ài tā chún shŭ yăn xiā]
Translated directly, this says 'To ruin my love for her was simply blindness'. It indicates bitter regret or pain from lost love; the decision felt wrong looking back. Or in another interpretation, the person feels they were blind to choose loving such a destructive partner.
