走得到你身边却走不到你心
[zŏu dé dào nĭ shēn biān què zŏu bù dào nĭ xīn]
Being able to get close to you, yet never reaching your heart. This conveys the frustration when physically present around the person you care about but feeling estranged emotionally—unable to connect truly or be accepted into each other’s inner worlds.
