How to win back a friend's trust depends on the other person's penchant for forgiveness.  When you try to win back a friend's trust, all you are talking about is forgiveness.  Forgive means that you are going to treat the offense like it never happened and become friends again. The problem with trustworthiness and forgiveness is that the willing depends on  the issue itself.

When a man cheats on a woman or vice versa, the woman may feel as though she is losing her dignity if she readily forgives the man for allowing another woman into his life.  There is a country song that tells women to never forgive or forget because of the damage that is done with fidelity and to move on.  But oftentimes the woman forgives the man and then find herself spending her precious time checking cell phone bills and coat, suit and jacket pockets.  So once infidelity is placed as the offense, the act of winning back the relationship has been thwarted.  A relationship between a man and a woman takes on a different genre than friendships between two guys or two girls.  Why?  Women realize that keeping a man satisfied with a relationship is difficult and when she loses out to another woman sometimes her whole life would be changed.  The woman may not only not want to win back the relationship, she may just label most men as flippart and unstable for a choice of kinder words.

When you have lost a friend's trust because of money issues, oftentimes the relationship can be won back with payment of whatever the loan amount was.  Just like the creditor will let you continue to use your credit card account if you pay the amount due, friends will be won back if you just pay them what you owe.  Do not ever consider an outlay of money as a gift.  Unless the friend specially say that the loan is a gift, he or she will want to have the money paid back. Friends are told to never use each other money so that they can remain good friends.  Even the good book say never a lender be because of the known consequence if the loan is not paid back.

If you have been careless with your friends secret information whatever the topic may be difficult to get back their trust.  Your chances for redemption depends on the person when you have divulged secrets that were privvy only to the two of you.  In some people's book  infringement upon their secrets to others is a reason to end friendships.  What to do if information leaked out about your friend that could have only come from you?  Be like a man and deny, deny,deny even if they have your voice recorded? No, just step up to the plate or phone whatever it may be and admit that you made a mistake and ask for forgiveness and that you would like to become friends again.  Winning back their friendship will have a lot to do with what the information was about and whether or not you vowed not to tell anyone else.

How to win back a friend's trust depends on the other person's propensity to forgive and the intensity of the offense that occurred when the trust was broken.  Trustworthiness is a gift to store and protect valuable information, an infringement of that usually result in broken friendships.  Learn from your experiences with this type of friendship and move on with the knowlege of what constitutes real friendship.
