What is he hasn t texted me back in 6 hours?

As an AI language model, I do not have any specific information regarding the context of 'he hasn't texted me back in 6 hours', so I can only provide general information about why someone may not text back in that timeframe.

There could be several reasons why someone does not text back in 6 hours, such as they may be busy with work or other commitments, their phone could be turned off, they could be experiencing some sort of issue with their phone or network, or they may not have seen the message yet. It's also possible that they are intentionally not responding or are purposely taking time to respond. It's important not to jump to conclusions without communicating with the person and understanding the context of their behavior. Communication is key in any relationship, so it's best to have an open and honest conversation to ensure both parties are on the same page.
