Edit: I already found proof of him emailing another girl to have fun with and I confronted him about it and he said he was just trolling. I also found dick pics of him on his phone and he said those pics were never sent to anyone and were only for him to see what he looks like. He swore he never cheated on me but my gut is telling me he's lying. I can't hire an investigator cause i don't have the money for that. Any free, reliable app I can download to spy on his phone? Thanks
