e-dultery
when you're too dumb to keep your marriage, so you just start talking to someone else online and forget about your spouse.
"My husband thinks I'm at work. I'm actually messaging my e-buddy about how much I hate him."
"My wife caught me messaging my e-lover. She said she was going to murder me."
"I told my husband I was going to bed. I was actually eating pizza with my e-buddy."
