e-dultery
when you're too stupid to keep your marriage, so you just talk to someone else online and forget about your spouse.
"My wife caught me messaging my e-lover. She said she was going to kill me."
"I told my husband I was going to bed. I was actually messaging my e-buddy about how dumb he was."
"My online fling said he was going to propose. I said I was going to propose. Now we're both stupid."
