is there a chance that someone can find real love with someone in prison? No games? Or more of a chance that the person is using the other person?

It is very rare that it ever happens the way you are envisioning it. Mostly, it is the inmate playing games to keep you around while he's doing his time. I've personally seen guys ride with a girl until the day they are released and then ghost them, cold as ice. Be very careful sharing your emotions and inner feelings with a dude with nothing to lose by stringing you along. He's hoping for commissary money, phone money and basic human interaction from the outside world.
