Judges 14:16

‘ And Samson's wife wept before him, and said, “Really you hate me and do not love me. You have propounded a riddle to the children of my people and have not told me the answer.” And he said to her, “Look, I have not told it my father or my mother, and shall I tell it you?” '

Samson was unaware of the threat to his prospective wife. So when she pressed him for the answer he was probably at first a little amused. Quite reasonably he pointed out that he had not even told his parents. But as her tears continued it began to ruin the wedding. Yet he still stood firm. If the solution leaked out he was a ruined man.

His wife must have been living in terror. She knew the threat hanging over her family and she had no doubt that they meant it. She was already looked on as Samson's wife, for such arrangements as they had were binding. Thus they would blame her for what ‘her family' had done to them.
