How do you catch a cheater that acts as if everything is ok in your relationship? I mean acts as if they are in love and want to spend every minute with you, how?
Without the help of others you might not be able to. See telling a lies part of it that's just one aspect though presentation matters as well that's how you convince people and when you told yourself something over and over again you can start to believe it is true which makes the LIE that much more authentic which makes it that much more difficult to destroy without irrefutable evidence or as I said before the help of other people.
