A Lie I Regret

I recently told my husband that I had met a friend from college at his age of 45 and we chatted for a bit. The truth is, I didn't even see her; she messaged me on Facebook asking how I was doing, and I felt so envious because it made me realize how long it's been since I've really socialized with anyone outside my marriage circle. I lied to give us something to talk about, but now I feel awful, like I'm hiding parts of myself from him just to maintain some kind of facade that we have everything under control.
