Lack of consideration after the declaration
In season 3, after Conrad's declaration of love on the beach, we see Belly break down (we can all agree that she'd been dreaming of this declaration for so long). She learns during this declaration that Conrad loves her & always has, that he's suffering from being away from her ans that he hates Jeremiah for seeing her with him. One might have thought that after this, Belly would regain some empathy that she would realize that Conrad has suffered immensely since Brown in season 2 and from his closeness with Jeremiah right in front of him because Belly & Jeremiah exposed their relationship (touching, kissing) clearly within a meter of him.
Except that after the declaration, Belly never manages to show any empathy or consideration towards Conrad. She even calls him heartless, even though in season 3, it's clearly her she is, as Conrad himself says, we see how much she's suffering so it must affect her personally. Despite all this, Belly continues to ignore Conrad's feelings, especially his pain and at dinner she kisses Jeremiah several times right in front of him, we should have seen her with a more closed, more hesitant expression, realizing that she's ultimately inflicting on Conrad what she herself would never have wanted to suffer from him, but it's all in vain.
Even in the last episode of season 3, Belly never manages to have any empathy or consideration for Conrad. That's really what made me sad about season 3.
