I dont think she is very fragile, she was very quick to get herself involved in claire balding and sarah burkes dramas and herself and her mafia were well able to make a big deal out of nothing.She is right to walk away from the page. Elaine comes across as extremely fragile and the older the kids get and the more needs they have she will not be able to cope. Her heartbreak is palpable. She yearns for a "normal " children and the regular milestones. She would be doing her children and family no favours going through all those emotions on Instagram.
I do however feel she is better off to step away from the page if people's opinions and genuine concern for what she chooses to show upsets her that much, Instagram is a choice and she needs to make the choice she feels is right for herself and her family.
