You can purchase, online, a set of numbers which you put into his cell phone that will reveal all. It's a program that tracks his phone usage basically. You will be able to see who he talked to, texted, and with enough money, see his geographical locations for the past 60 days. The caveat of this program is he won't ever know you put such a thing on his cell phone. You go online to a website to retrieve the information. And it only takes moments, say while he is in the shower or something, to input the program onto his phone...that being said, the real question is, do you truly want to continue a relationship with someone you do not trust and feel forced to question and perhaps track their activities? There really are plenty of fish in the sea as the saying goes. Good luck.
It's much easier to just be the quiet one.
