Is it true, what they say, about how a person always knows when their significant other is wandering? They say to listen to your gut; that your gut is never wrong. That to listen to the heart is the first mistake.
But what about when there is no real evidence of said liaisons and all you are going on are feelings?
When you go looking for something, are you really going to find it, or are you only going to find what you THINK you will find simply by fabricating and stretching reality to fit in with your disillusioned state?
Even a rock can look like a crocodile in the darkness.
