Why didn't MrCollins accept Elizabeth's rejection of his proposal?

Answer 1

Mr Collins truly believed that this marriage would be advantageous for Elizabeth, and he had no doubt that she would accept him. When Elizabeth responded to his proposal with a "no", Mr Collins just thought that she was "playing lady games" and wanting to be asked twice. He honestly thought that she wasn't serious with her response so he refused to accept it. Also, Mr Collins has pride in himself and her rejection would've been a low blow, especially after he was so confident earlier.

Answer 2

Mr. Collins didn't accept Elizabeth's rejection because he believed it was simply a formality and that Elizabeth was playing hard to get. He was also motivated by his sense of entitlement and his desire to fulfill his duty as a clergyman by securing a wife. Additionally, he lacked self-awareness and social cues to understand Elizabeth's true feelings.
