[Grammar] “I will grow old,so will you.But those love words I say to you will never get old.”

[Lesun]

Is there any mistake in this statement?Somebody says it is not proper to use"so will you"here...I am really confused...plz give me some help plzthx

To be grammatical, you need an "and" there.
I will grow old, and so will you.

I also suggest that "love words" would be better as "words of love."
