I am a Notre Dame fan but I do not know, nor have I ever met Manti. I have FOLLOWED the story because I am a fan, and I have noticed that many people are commenting on the story without having read all the information. This man was duped and did question it himself on several occasions, however, due to the elaborate nature of the hoax (and being naive), he remained vested in this fake relationship.
He made the mistake of lying when he felt embarrassed and humiliated (we have all done this at some point), instead of telling the truth immediately. Unlike us "regular" people, he was facing an entire nation and every media outlet hanging on his every word. I like to think that I would have caught on to the scam right away, however, we don't know what he was taught or how he was raised. In addition, when "women" and "emotions" are involved all men get "dumb"every so often. Either way, the dude will never live it down and this story will follow him for the unseeable future...
