Could have been him not wanting someone to know he was in a relationship. If that were the case then him lying about it shows that he's definitely hiding something. Because relationship statuses don't just change themselves. But there could potentially be someone tampering with his account. You never know these days. The timing of the change is a bit coincidental though considering he's about to go away on a trip.

He changed it for a reason, and if he's hesitant about it then that means he doesn't want someone to see sense he's living for his hometown. I would straight up ask him if he just wants to break up or not sense he pulled that stunt.
