If someone turns out not to be the way you imagined and perceived them to be, isn't that your own fault?

Someone not turning out to be what we perceived them to be is one thing, and them projecting themselves one way while being something completely different is another. We can truly only go off the information we’re given in any scenario. But that’s also why we have gut feelings and intuition to help keep us in tune to the truth that may be hiding under the surface. It just depends on how weakened we are by what they’re giving us to let that unspoken truth outweigh the empty words that are being spoken by someone who knows exactly what they’re doing.
