你的心太大我容不下
[nĭ de xīn tài dà wŏ róng bù xià]
'Ni De Xin Tai Da Wo Rong Xia Bu Xia' could be translated to 'Your heart is too big that I cannot accommodate it.' On the surface, it may imply inadequacy or the impossibility to understand or reciprocate feelings because of one’s own incapacity or differences.
