只能默默看你 就是说不出口英文怎么说

Without saying anything, all I can do is just looking at you silently.

为了突出强调的感觉，也可以这样说：Without saying a word, what all I can do is just looking at you silently.

I can't say a single word, looking silently at you

COULD EVEN HARDLY SAY A WORD WITH LOOKING AT YOU SILENTLY.

love u more than i can say ??
