How do you recover lost trust? In a person? In an idea?
Bonus: If someone lets you down or betrays you, how do you learn to forgive? And can you possibly learn to trust them again? Why or why not?
This is something I could speculate about all day. Personally I think recovering trust is a life long process. Once you have lost trust in anything, a person or an idea, it is difficult if not impossible to regain it. You really have to be determined and make a constant effort to re-build trust. People that are more trusting are probably happier and better adjusted than the more cynical ones among us who routinely question and look for ulterior motives.
It is usually better for your health and well-being to try to forgive someone but sometimes it is not possible to forgive someone who has wronged you or hurt you. Some people can be forgiven and awarded your trust. Unfortunately there are some individuals out there that simply cannot be trusted under any circumstances. It is more important to forgive yourself.
