There should be no need for your wife to show any of the above signs. She shouldn't be so caught up in her text messaging that she forgets you. If she is with you, her husband, then who else could she possibly texting all of the time that is so important? It is okay for your wife to occasionally text her friends and family but when it is nonstop then something suspicious must be going on. Your wife may be texting another man behind your back and may possibly be having an affair. When you ask your wife who she is texting she should be able to tell you without any regret. If you ask your wife to look through her phone you should be able to do so without any problems and your wife shouldn't have to erase all of her text messages because this shows her talking to someone that she shouldn't be talking to.
If your wife will not show you her phone and you want to know how to access my wife's text messages then you could try to take your wife's phone when she has left it laying around. Without asking, so that your wife doesn't erase her inbox messages, you could simply take your wife's phone and look through it to see who she is really talking to. However, what if your wife catches you doing this? This would obviously result in a huge argument and could make a little situation like this develop into something that it shouldn't. There has to be a better way that can show you how to access my wife's text messages.
The most effective way to do so that will allow you to find out the truth anytime and every time is through cell phone spying software. This software records all of your wife's text messages and uploads them to your personal account. Even your wife's deleted text messages are recorded by cell phone spying software. Your wife will no longer be able to text people that she shouldn't be talking to behind your back because you will be able to find out whenever you please without your wife ever knowing.
