In short, it's just one thing - if Robert Thomson hadn't given her hopes earlier, she wouldn't be like this now. Robert Thomson does bear some responsibility for her change.
Robert Thomson sneered: "It's a joke. Regardless of hope or not, she should be clear in her heart that I never liked her from the beginning. The reason I proposed to her before must be known to her, which was to anger Emma Smith. For this engagement, I have broken up peacefully with her, and all the responsibility lies with me. I also gave your company a certain concession in the contract as compensation. She is an adult, and her emotional loss of control has nothing to do with me! Don't shirk the responsibilities she should deal with!"
Ethan Martin's face turned pale. He knew that he could only use emotions to move Robert Thomson. A woman trapped in love may do impulsive things and should be understood.
