Answer: Words are cheap, it’s the actions that speak. He certainly does not sound dependable and relationships need to have a foundational level of trust. I would ask him “straight up” the following questions and carefully listen for truth; Why do you say your coming and then you never show up? What happened the first time? What happened the second time? And finally, why should I believe you now? If his responses sound like he just made up the answers, then I would ask him one additional question as a truth/pride check; Have you ever lied? Watch for the response, hesitation or attempted misdirection to that question would most likely show deception. A direct Yes response would show some honesty, A no response would reflect dishonesty. Other than that, I one might consider a three strikes and you’re out rule.
