I bet bunch of single guys are telling her she should leave him.
I don't know her or her husband personally... but anyone thinking they can change her or her husband once they are single again will be greatly disappointed.
Real growth comes from within, it does not come when you ditch your current partner and get a new one. Sooner or later, any underlying issue you had will come up and the drama will start again.
My analogy is this... if you're a bad driver, it does not help how many new cars you drive buy, you will still get into accidents. However, if you fix your driving skills and become a better driver, you will have less accidents or no accidents... even if you have an old car like me and don't have a backup camera, lane departure warnings, or blind spot indicators.
