She is mental, if anyone deserves to be put into a mental facility it is Skylar. She should be locked in a padded room and throw away the key. Those kids are way better off with Walt. He is living a dangerous life but he would do anything for his family. Skylar on the other hand has shown that she would do anything TO HER FAMILY, just to punish Walt for not catering to her every psychotic whim. As long as she gets what she wants when she wants it, nothing else seems to matter to her, not even the sake of her own children. The best thing walt could have honestly done was to have her committed as soon as possible. Sure it is not ideal at all for 2 kids to lose their mother. Emotionally they would have been much better off just knowing mom had a mental breakdown and had to go away for a while. As oppose to what they did end up going thru over the course of the show and beyond it.
