Answer:
It causes the bride to blush and makes her content.
Step-by-step explanation:
The text makes it clear that the bride was pleased by the words spoken by her beloved and that made her blush. Because her fiancé spoke beautiful things about her and she was glad to know he saw her that way
The part of the text that makes this clear is: "She turn’d, and she blush’d, and she smiled, And she looked sae bashfully down".
