Blanche realized that Stanley was an impulsive man when she first met him. She sensed that he was about to create difficulties for her if she continues to stay with her sister. He was the kind of man who sought pleasure from every woman. Thus, Stanley attempts to warn Stella about this but she disregards her. However, it makes Stanley go crazy to ruin Blanche's esteem.
Explanation:
As per the question, the given quote implies that Blanche sensed the unruly and fractious character of Stanley at her very first meeting with him('The first time I laid eyes on him I thought to myself, that man is my executioner').

She knows that Stanley wishes to ruin her('That man will destroy me') as she tried to reveal his impulsive character to Stella.
