If you lived with someone and planned a life together it's not so unusual to expect things to go back to how they used to be and have hope. We see things very differently a few years later. It's not even impossible that they do get back together but I think he wouldn't want the public life to continue like that. I don't think she owes anyone an explanation what happened and why and it's very tacky that people ask it directly, harass her family etc. but I do think she should have stayed offline longer or handled her public accounts a bit more professionally with a short statement, time off and then slowly back to normal (new normal).
