Most Helpful Girl
If you really want to take drastic measures the IP address of the messages can be looked up. It proves the profile wasn't made from any of your devices... But like I said that's taking a drastic measure. I would be very hurt by this as well. I wouldn't ever want someone I loved accusing me of something so petty. Could it possibly be that he's fabricating this to create more animosity and distance so the break up will hurt less? I find many people especially men tend to do that.
