You're texted by Nick about living in town? (5)
I believe the answer is:
urban
'in town?' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for urban that I've seen before include "Name adopted by eight popes: built-up" , "Not rural" , "Relating to cities" , "Living in a town" , "Relating to a city/town" .)
