It’s obvious to us viewers that Taylor didn’t like her because we saw his conversations with the guys and in confessions. But he never gave her a reason to believe he didn’t because he kept telling her “we have a strong connection.” I think she’s just telling Clarke to keep her options open so she doesn’t get blindsided like she did.
I think they were never compatible and he lied when he was with her so he could stay in the villa until he found someone who was his type. Him and Clarke get along well and I honestly thinks he genuinely likes her. But from Olandrias POV, she thought that they were a great couple too and he just left her but that was never the case. He never liked her as much as she liked him.
