How could he argue against her feeling horrible about kissing ‘another man’?
Really his only response is to tell her he is Superman which she keeps cutting off.
He had tried to tell her that he was Superman,
He should wonder why she cut him off so much.
tried to explain that she hadn’t technically cheated on him,
Which means in some way she did cheat.
and tried to convince her that she was better off with him than without him,
This would only be workable if she would tell him her true concerns.
She would not listen to reason, but she had listened to him when he said he was scared for her safety.
He should have focused on telling her more important truths first.
Lois, who wasn’t afraid of anything, had agreed with him that her life could be in danger, should they continue to date.
Which should clue him into there being other issues.
Sometimes, he just couldn’t understand her pigheaded logic.
They both are pigheaded though.
