He's Honest About His Mistakes
The ability to own up to mistakes is the single, biggest indicator that a man will be 100 percent faithful to you.
The importance of this trait can’t be overstated. A guy who hides his mistakes from you tells you that he doesn’t trust you. And if he hides bigger mistakes that involve you, such as with finances or legal issues, he shows a disregard for your safety and wellbeing.
This is the kind of guy who runs when things get tough, and who will likely stray as soon as any hint of relationship trouble comes along.
An honest and faithful man, though, is open about his mistakes. If he forgets to pay a bill or overspends on something silly, he’ll tell you, and he’ll learn from the experience. This kind of man only gets better with time, because he uses each mistake as a springboard to find new strengths.
Best of all, he doesn’t run.
Only men who are faithful are willing to own up to their mistakes every single time. If they’re not, they won’t care about establishing the trust that is such a vital part of any relationship.
