Is there any way I can get all the text messages send to het phone to be sent to my phone or a website? i have full control over the phone when i need it, but whatever methord has to be covert, she'd kill me if she knew.
It's not only unethical and the sign of a disastrously failing relationship, but tapping another person's phone without their permission is illegal. Consider that you might not just end up without a girlfriend, you might also end up in prison as someone else's girlfriend.
OK, enough ethics. We have several other threads with similar content. The OP has responses which cover the technical issue and point out the potential legal pitfall.
