There's a wide range of possibilities, from a health emergency with the newborn, to a health emergency for her, to a legal emergency for her or, more likely, Marshall, to losing her housing. Maybe she's in a shelter hiding from Marshall. Whatever's happening to make Melinda stay away from the internet, one thing is for sure: it won't be anything that actually improves her and her children's lives. I feel safe saying this because nothing Melinda has ever done is in the best interests of her children.
