“abc def” should match the following regex because “abc” and “def” both have 3 characters
/([a-z]*) ([a-z]*){\1.length}/
Is there a way to do this in Ruby?

The set of strings you describe do not form a regular language. It cannot be matched by a regular expression. It’s one of the classic examples of languages that can’t be matched with a regular expression (another is testing for matching parentheses).
Just compare the lengths of the two strings in ordinary code.
