Whether or not it is considered rude depends on the specific circumstances and the established communication patterns in your relationship with the guy. Different people have different communication styles and expectations, so it's essential to consider the context before making any judgments.
Here are some factors to consider:
Previous Communication Patterns: If you both usually communicate regularly and he suddenly goes silent without any explanation, it might be seen as inconsiderate or rude. However, if it's not typical for him to text throughout the day, it may not be a cause for concern.
Nature of the Plans: If the plans are casual or flexible, like hanging out at a coffee shop, it might not be as crucial for him to confirm. However, if the plans involve more significant commitments, such as attending an event or meeting at a specific time, confirmation is generally expected.
Emergency or Unforeseen Circumstances: There could be valid reasons for his lack of communication, such as an emergency or an unexpected situation that requires his attention. In such cases, it might not be rude, but it's thoughtful to let you know as soon as possible.
Communication Preferences: Some people prefer to finalize plans at the last minute or have a more spontaneous approach. If this aligns with his communication style and you are comfortable with it, it may not be rude to you.
Expectations and Boundaries: If consistent and clear communication is essential to you, it's important to set your expectations and communicate your boundaries with the guy.
In general, communication is a vital aspect of any relationship, and open and honest dialogue can help clarify each other's expectations. If you find his lack of communication bothersome or disrespectful, it's okay to express your feelings and concerns to him. Keep in mind that he might not be aware of how you feel, and addressing the issue calmly and constructively can lead to a better understanding between both of you.
Remember, people have different ways of expressing themselves and handling communication, so it's crucial to maintain empathy and considerate understanding when dealing with such situations.
