Why was "to" used at the end of the sentence?
"Get back to" is a phrasal verb in question. Because the speaker is referring to a location, his "own life," the preposition "to" is added to the end. Generally, "get back to" will be followed by an object or location, thus requiring the preposition "to" to link the words together. Ex. I will get back to you tomorrow. Ex. Are you excited to get back to school next week?
