* Good friends don't keep saying things to you that are hurtful and upsetting to you. You should communicate your feelings to your friend and let them know what things they are saying that hurt you. You can't ask for an apology because it would mean nothing and it's up to that person after you have talked to them to apology to you on their own. If this doesn't happen and your friend continues their behavior then consider this ...'if a person makes you feel miserable 85% of the time in your relationship you need to move on from them.' The reason for this attitude is if that person refuses to respect you enough to change their attitude towards you then they will drain all your energy and you won't have enough energy left for those that do respect and love you. It isn't how many years you have known the person, but the trust and respect each of you give each other.
you maybe have to apologize about what you did to he / she . give it a try and who knows ? if they don't accept your apology , then it is their problem .
If you have done something that has offended your friend, in most cases it is better to apologize verbally. An apology in writing presents a degree of formality that would seldom be needed in the context of a friendly relationship.
You just be sincere and honest with your apology and state what it is that you know hurt them. Reassure them that it will not happen again and see to it that it doesnt.
Something must have happened for your best friend to suddenly hate you. If you did something wrong, admit to it, apologize and see if they will accept the apology and more on. If you don't know why they hate you, ask them. It may just be a misunderstanding that has got out of hand.
About all you can do is apologize and try to make up for it. Don't push her (or him), but be patient and let her absorb your apology. If she doesn't come around and can't let the issue go, then all you can really do is move on.
Just apologize. It's not that hard to do, so why bother asking the question? Just say "I'm sorry" and just get it over with. Your friend may accept your apology, they may not. It depends on how angry they are at you.
Apologize.
If you are going to write a letter of apology to your Arabic friend because you asked for his friend's number, then you can write أنا آسف. لم أكن أقصد أن تؤذي مشاعرك., which means, I am sorry. I didn't mean to hurt your feelings.
Moj najdrazi prijatelju.
The best way to apologize to a friend that is mad at you is to do it in person. That way the friend can see that you are genuinely sorry.
Prior answer: you tell her your friend was lying and apologize. Nay... do not lie. It is never wrong to like someone. An apology is fine, though unnecessary. Give her space and do not be pushy. Otherwise, treat her like you always have (hopefully with respect and courtesy).
* A best friend is someone you trust and you let your friend down! You preferred to believe someone else's gossip rather than to face your friend and get the truth. You owe them a huge apology and you'd better hope your friend has more trust and faith in you than you have had with them. Don't listen to gossip! Call them up and ask them to meet you somewhere and then look them in the eye and apologize and mean it!
