Honestly, in that case the only thing you can do is wait. You've done everything you could, and everything you're obligated to. You can't take back what you did wrong. All you can do is apologize or do an act of contrition. It's up to them to forgive you.

You could try again later, after some time has passed -- a few days, or a few weeks. It depends on your friend and how exactly you wronged that friend. But it's still up to the friend.

If I wronged a friend and apologized for what I have done and she refuse to accept my apology then I will just accept her decision. Women especially have emotions that cannot be turned on or off like a switch. Sometimes it is hard to forgive and even harder to forget. I will respect her decision because I cannot do anything about it. It is out of my hands.

As long as I have done what I think is right, then I can have a peace of mind. Maybe, time will heal her wounds and she will accept my apology in the future. But I will constantly pray that she will in time be able to forgive because she is not hurting me in the process only herself for that matter.

Nothing, if someone does no longer values the friendship enough to accept an apology then the friendship is over.

Tell the person to call you if they can ever forgive you then hope for the best.

If they never call you have to live with that.

I would likely try to explain to her as best as I could what specifically led up to the incident that caused me to wrong her and hope she would understand. I would tell her that I did not intentionally set out to wrong her, but unfortunately the way the events played out, she ended up being hurt by my actions. I would ask her what she would have done differently if she had found herself in a similar situation and what she would have liked me to do in place of my actions. Then I would provide a rationale for my behavior and why I thought it was the best thing to do at the time. If after I provided my full account and extended my utmost apologies, my friend failed to forgive me, I would likely remove myself from the situation and give her some space to absorb the information I provided. After she recovered from the initial impact of the incident, she could then (hopefully) regard the situation in a more open-minded manner and decide how she would like to proceed. Whether she forgives me or not clearly depends on her willingness and ability to view the situation from my standpoint. I would likely feel better about myself if I have given my friend the whole truth on the matter so that she is well informed on what happened and why. I would simply give her as much time as she needs initially to process the incident and then tell her I would check back with her to see how she feels. I would then contact her after a few days or weeks with the hope that she was able to overcome most of the hurt I caused. While she may not be able to forget the incident, hopefully she could find it in her heart to forgive me and trust me again. Sometimes time heals all wounds.

I apologized to a former best friend just yesterday. I just wanted to make peace and put the past behind us. Both of us were wrong in our behaviors and I wanted to extend the olive branch. She chose to ignore me. I was not judgmental when I gave my sorrys. I was genuine. No digs at her; only how sorry I was that our friendship had died & that I wanted that to change. I am happy with that. I can sleep soundly at night because I know I did what was best for everyone whether it changes the situation or not. I have let my hostility about her die & that could only happen if I humbled myself and apologized. My conscience is clear! I am free :)
