How can anyone ship OQ after he was such a jerk? He was rude and prided - as if Regina was begging him to cheat on his wife.
Since when is pride a bad thing?
He would not cheat on her nor leave her because he is a man of honor. He knows Regina needed to be reassured of his feelings for her, but that he couldn’t break his vow. He had to diminish her hope after reassuring her that what they had was real. That’s not easy. He’s also still grasping the situation. His WIFE who birthed his child, who he LOVED, who he MOURNED, is back. That’s not easy to let go of. If he was to cheat or up and leave her in a new world where she isn’t familiar, he’d be considered supreme dickhead king of all dickheads and that’s not something you would want to bring into a new relationship. I wouldn’t date a guy who would leave someone for me because in the back of my mind, I’d worry he’ll eventually leave me.
