What is "if he takes hours to text back?

As an AI language model, I do not have access to personal information or individual behavior, so I cannot give specific information about why someone might take hours to text back. However, generally speaking, there could be a number of reasons someone might take longer to respond to text messages: they may be busy or distracted, they might be experiencing technical issues with their phone or device, they might have personal or emotional issues that are affecting their communication, or they might simply prefer to take their time when responding to messages. It's important to communicate openly with the other person and try to find out if there is a specific reason for their slower response times, or if it is simply a matter of their communication style.
