Is one of the other choices correct also?

Question

Eres muy pesado. ________You are very annoying. Leave me alone!¡Que me dejes en paz!¡Dejarme en paz!Hi, is “Dejarme en paz” also correct? Gracias, Shirley.?

Answer

Hola Shirley
Dejarme en paz isn't correct. Although you may here the infinitive used like this sometimes colloquially it's not considered correct. The infinitive used in "commands" is more restricted to public signs of the type "No fumar". Here's a lesson on this. 
Saludos

Answer

Is déjame en paz correct then ?

Answer

Ashlyn,

"déjame en paz" is correct, yes. Here there is the imperative with the pronoun attached "deja - me", but what Shirley was asking was if "dejarme en paz" was correct or not. (using the infinitive dejaRme en paz)

Saludos
