Quick thoughts, but some of the guys here will do better...
But, not good at being mean or short... do I still remain pleasant with her? - Be calm and civil like you would to a neighbour or slightly odd acquaintance. Still spend time with her? Should I stop telling her what I'm doing. - Not much. Yes, other than practicalities. And when I'm doing it? She complained about not being able to reach me via text. - Tough. Welcome to the new world she has made. She fired you from being her H...different rules apply now. She's breaking down afraid she will be fired from her job and She is the primary breadwinner in our M. - Again, tough with a validation of 'gosh that must feel stressful'. Maybe you need to get a different job that earns more. Guess that will be helpful GAL if you do end up divorced?
She of course has already noticed I've lost weight in my rapid GAL plan. - GAL is for YOU. Meh to if she notices, just meh. The situation won't be fixed by a 6 pack (although it might make you feel good!)
