我怕见不到你我怕留不住你
[wŏ pà jiàn bù dào nĭ wŏ pà liú bù zhù nĭ]
In English would be 'I'm afraid of not seeing you, I'm scared to lose you', revealing one’s insecurities. It's a vulnerable expression of someone being scared of missing someone important out of their sight and unable to hold onto this precious relationship.
