除了你， 我再也不会喜欢上其他的男孩！ 用英语怎么说啊？

You know , if u left me. I will never in love again.
跟你说的意思有些出入。。但是个人感觉比你那么说效果更好。。

Except you, I'll never fall in love with another boy forever.

Except you , I can not like again also other boy

呵呵，谁都听得懂！！

Besides you, I will never fall in love with any other guy.

i'm nuts about you,i won't love any other boy forever.
