My wife is bored and doesn't reply by texting.

There are three reasons. First of all, it's because she thinks you don't care about her at all, and you can not contact her for a week. When she thinks about this, she will be sad and will not reply to you angrily. You calm her down and she will tell you what she thinks. Second: She has been too busy recently to contact you. In this case, it can be said that her mind is not on you. The third type: she is used to not looking at her mobile phone, so she didn't see the text message.
