there are several potential explanations for such behavior:
Busy or distracted: The person might have opened your message but got busy or distracted with something else, and they haven't had the chance to respond yet.
Unsure how to respond: Sometimes, people might not know how to respond to a message, especially if it requires careful thought or if they are not sure what to say.
Waiting for the right time: They could be waiting for a more appropriate time to respond when they have more time to engage in a conversation.
Lack of interest: While it's not always the case, leaving messages on "opened" without responding could indicate a lack of interest or investment in the conversation.
Misunderstanding: It's possible that they misunderstood the message or its intent, leading to uncertainty about how to respond.
Technical issues: There could be technical issues with the app, causing messages not to register as read or preventing them from sending a response.
Avoidance: In some cases, a person might intentionally leave messages on "opened" as a way to avoid confrontation or a conversation they don't want to have.
Social norms: In certain social circles or situations, some individuals may consider it normal not to respond immediately or at all.
It's important not to jump to conclusions or make assumptions about someone's intentions based solely on their response time or actions on social media. Instead, if you're concerned about the situation, consider having an open and honest conversation with the person involved to clarify any misunderstandings or address any issues directly. Communication is essential in understanding each other's perspectives and maintaining healthy relationships.
