Final answer:
Shay and Charles do not have a healthy relationship because there is a lack of communication, respect, and safety due to Charles' temper and Shay's fear.
Step-by-step explanation:
Shay and Charles’ relationship does not exhibit the characteristics of a healthy relationship. It seems that there are issues with communication, respect, and boundaries. Charles making a last-minute decision to cancel their date and choosing instead to hang out with his friends, coupled with Shay's reluctance to speak up due to fear of Charles' temper, suggests an imbalance of power and a lack of mutual respect. A healthy relationship is built on trust, open communication, safety, and mutual respect, and Shay’s apprehension and Charles’ behavior seemingly violate these principles.
