The 23-year-old hit back at accusations that the ITV2 programme is faked, adding that there is genuine hurt caused by comments and incidents involving the cast.
"It's about 80% real and that's what makes certain things really upsetting," he told the Mail On Sunday. "One minute you can be chatting to someone, thinking they are your best mate, then you see them slagging you off and bitching about you on camera."
He added: "It's really hard to trust people and to know who is really a friend."
Falcone revealed last month that he is working to restore his relationship with Lucy Mecklenburgh following her affair with their TOWIE co-star Mark Wright.
"We're still trying to establish trust," he said. "This is the first relationship where I've given all my trust and it... well, it hasn't backfired, but, obviously, I've ended up really hurt.
"Now it's just about building it up again... It's not about forgetting - it's something we both have to learn from. It will always be at the back of my mind."
Former TOWIE star Linzi Peel claimed in April that the show is almost entirely "fabricated".
