Awww I feel for your heart, my friend but don't be harsh on yourself; you didn't know any better at the time! The great news about trust is that building it is always reversible as long as the person is accountable! The most important deposit, to me, to elevate the trust reserve is to apologize sincerely (and quickly whenever is possible). The sincere attribute is crucial. It should be felt. So nothing is lost. You may always model that lying is not okay, that it might happen sometimes while being fueled by good intentions, but it doesn't make it any right, and that's why you owe him an apology! 💙
