Cause it's clear your husband is a liar. let's not forget how you ended up moving straight from the hospital with a newborn and in the midst of divorce 60 days later. and how he tried to railroad you in the divorce, buttttt I digress.
Gossiping and spreading rumors is a way of life for a narcissist. They gossip about EVERYONE behind their back. Narcissists make people feel "special" when they're feeding them malicious gossip. Don't be fooled! You're NOT special.
