What's the meaning of "不见面也有不见面的好"? I really couldn't understand the meaning of this sentences. 

见面 means to meet, to see
不见面 means not meet, not see.

不见面也有不见面的好。

But I really couldn't get what it is saying.
We can break this up into three parts


不见面 - to not meet 
也有 - also has
不见面的好 -  the good aspect (or benefits) of not meeting


There's also benefits of not meeting (or not seeing (each other)).
