What is love?

Fictional emotion in my opinion  - - ;;

What is love? Why you love her? Why you married her?  It's hard to say. Love her big eyes? Love her long hair? Love her beautiful face? But if one day you meet a lady  whose eyes are bigger than hers, whose hair is longer than hers, whose face is more beautiful than hers, are you ready to divorce her and marry another one? I love her ,but it's hard to say why . Maybe it  just a feeling . I love her ,I know I will share joys and pain with her in my rest life.-----------------------------That are from a Chinese singer,Xietingfeng(谢霆锋). I translate them into English.Maybe they are just the answer for your ask.

Thanks your answer
