A confidant is a trusted friend we can talk to about personal and private things.
Choosing one is very hard because, at the end of the day, a secret must remain a secret so we must take caution in spilling them to a friend unless he/she is our confidant.
Here are some ideas I shortlisted from Janis Long Harris, to consider:
...you can trust
... who can keep a confidence
... who will respect your boundaries
... who will give you perspective
... who will pray for you
... who is wise and has more experience than you
... who values commitment in marriage
... who will keep you accountable without unjustly condemning you
... Of the same gender, or a married couple
... who will not be negatively affected by your confidences
"Always be careful of your friend who loves your enemy; you either trust such a fellow for your life or for your death."
