我爱你你爱她你妈了你真瞎
[wŏ ài nĭ nĭ ài tā nĭ mā le nĭ zhēn xiā]
'I love you, you love her, damn you are blind' describes disappointment or frustration. When two people are connected through a love triangle, especially when such choice hurts another's affection, this phrase sarcastically accuses the second person for not noticing the speaker's emotion and seeing only the third person.
