Added (1). he has an iphone 4s and I have a 5c

Your a sneaky girlfriend. Your relationship won't last long.

Perhaps you shud re think you're relationship you obviously don't trust him if you're paranoid, It's invasion of privacy no offence

Obviously it's alot more secure then a silly question like this.

I assume that it is theoretically possible to copy the messages database. However, it's most likely encrypted and even if you somehow decrypted it, there would be other things wrong.
This involves jailbreaking both of your phones and doing a **** ton of things.

Since you're asking this, you probably have absolutely no ******* idea as to what I'm talking about.
You'll miserably fail and won't achieve your goal.

Unless you don't care about morals and ethics and laws and work for the NSA, you don't have a chance.

If you both have same Apple ID you can have his message to your iPhone. Do install Leo Privacy Guard to you Smart Phone. It will make your Phone totally secure by hiding your personal images and videos.

Just break up with him. You of course think he is cheating or lying and therefore want to spy on him. That is rude. I hope he breaks up with you. How could you be so cheap?
