Lying is never really a good idea, imo. If you don't like being lied to, then don't be a hypocrite and lie to someone else.
Especially about something like that.
The guy I was seeing, told me he was married, and then I found him on a social website and his status was as "divorced". When I asked him about it, he said it wasn't him. It was a photo of him, or someone identical (a twin?), with his name, living in the area he lives in, the University that was close to where his parents live, and with the same interests as him.
His age was also a few digits older.
The problem with lies is, when you start, it never stops.
