From a source. Another spin on the rumor and fallout.

Marge’s ex friend was so pissed she wasn’t chosen as a housewife or friend of she turned on Marge. She met up with Jen and Teresa back in February. She told them a bunch of rumors. One of the rumors was about Melissa. Teresa and Louie told Joe “privately” in February about the rumor. They tried to break up the marriage.
And when it came to the show at finale Melissa outed Louie and Teresa for telling Joe this rumor behind her back. Danielle also inserted herself at the finale about the rumor. Dynamics are very weird and shifting daily.
