Final answer:
Beatrice's attitude toward Roy was neutral; she only liked him without a deeper emotional connection.
Step-by-step explanation:
Based on the provided text excerpt, it appears that Beatrice's attitude toward Roy can be described as neutral. The passage indicates that although Beatrice was married to Roy, she only 'liked him' and did not experience a strong emotional attachment. She was honest about her feelings, and Roy, consumed by his own emotion, had to contend with the fact that she had never incited jealousy in him. Hence, her sentiments towards Roy were neither particularly positive nor negative, but somewhere in between, signifying a neutral stance.
