How do I find out someone's text history?

My girlfriend has an iphone 7 for T-Mobile. Every thing is in my name. I want to know if there's a way I can view her text history without her knowing. Any ideas?

You gonna trust her. It is invasion of privacy

So insecure, jeez. Mad tragic

There are apps you can buy to monitor someone's texts. Google it

That's still technically an invasion of privacy sooo you'd be better off leaving that can of worms unopened.

What you are asking is illegal in many countries. If you are so insecure it's time for you either to start trusting your girl friend, or go and join a monastery. Spiritual guidance might help you.
