But he's not all she has now. She doesn't have to go back to Noah since he has no claim over her, but say he wants to force her, she has her boss. While I don't particularly like him since he's boring, he has power, money, and the care to protect her. She also doesn't need anyone. She could pack it all up again and leave once more
Everyone saying she should just marry him totally ignoring his obvious red flags that he never had when she did marry him in the past
He wants to live in this past fantasy while she has fully moved on with her life and would be happy without him, something he cannot be
She doesn't need him outside of money for her nephew's care, but personally she has no use for him and clearly doesn't want his help with her nephew. He is also acting exactly like Count Noah, even looking quite like him, so people fighting for them to marry now are crazy given the same people hated Noah.
The way he is treating her rn is disgusting and marriage won't fix that, only make it worse. She had a mental break years ago and took the time to improve herself while he fell further into that madness. They cannot be together because they cannot meet at the same level mentally and being with him will only degrade everything she has built for herself, including most importantly, her mental fortitude and maturity
