When do you use "de ellas" (de + pronoun) ?

Question

Why is the last sentence written as "y no abusemos de ellas"? I thought that it should be "no las abusemos". Is there a rule for when you put "de ellas" at the end of the sentence? I thought that you weren't allowed to have pronouns on the end of sentences in Spanish.

Hola Kimberley
the verb abusar in Spanish is used with the preposition "de" unlike in English (no preposition).
We say "abusar de algo" or "abusar de alguien". If used with a pronoun, you need these pronouns:
mí, ti, él, ella, usted, nosotros/-as, vosotros/-as, ellos/-as
For example:

Estás abusando de mí.
El alcohol es malo. No abuses de él.
El jefe nos explota en el trabajo. Está abusando de nosotros.

I hope this clarified it.
