Uhhmm lets see . What you can do is apoligize sincerely to your friend and explain the reason why you did it . But dont get to afraid to tell them ; . Im sure they will understand .

well, if u want 2 apoligize go ahead and say it!!! 2 start it off, say wut u did wrng, if ur scared 2 admit it, say tht 2, its important VERY ESSENTIALLY IMPORTANT 2 B HONEST, best wishes!!

The best way to apologize is to do it with no excuses. There is no justifiable excuse for betraying a friend unless it's life or death or something that you know they would understand and forgive. Anything else, simply deserves a heartfelt apology and time for them to get over it and forgive.Even though you might wish that they'd immediately forgive you and things could return to the way they were before this happened, keep in mind that it might not right away or ever. Trust really does have to be built overtime particularly after it's been betrayed.So my advice is to be real with your apology, include no excuses, and accept whatever fate might hold in store for you. Hopefully, your friend will understand that everyone makes mistakes and be willing to forgive you.
