Should she be grateful that he likes her and just accept him?
Why should she do that?
Who is he?
Thanks to Diamond's continuous brainwashing which also opened her eyes, she knew that settling for less wouldn't do for her.
She wanted to meet someone who will love her and embrace her even with her flaws. She didn't want to compromise at all and accept because that's how it is.
Why should she be the one doing such?
Even if Sean's family was rich. That was his family and not him. Why shouldn't he do something for himself?
Moreover, Diamond was doing all that for her sake. So why should she support a stranger and cast aside her own sister?
As a result, the conflict dragged on for months. Every time they meet, things never ended well. Whenever she tries to talk to him, let him understand, or rather let him explain himself, he would always speak nonsense. Things that don't even make sense, and at the end of it, they would argue and part without speaking.
