Your best friend is not your best friend at all because if she was she would never hurt you in this way. She did so because she can and some women are jealous of their friends if they are married. Also when your best friend is around both you and your husband she may have fallen in love with him. Both your best friend and husband are to blame, but mainly your husband as he could have formed the word 'no' at the very beginning and chose not too. You would be wise to get rid of your best friend and let your husband know you are not putting up with him cheating. Good friends simply would not do this to hurt another friend.

Get marriage counsellor. Some mature common friend or relative is the next best.
She is not your best friend if she slept with your husband. Like any relationship a good one should involve trust and loyalty and your friend has taken full advantage of you and hurt you very deeply. Good friends do not do this! Even though the responsibility lays on your husband's shoulders because he should have never slept with her, both are at fault. Unfortunately and sadly to say you have been hurt twice over by your husband and best friend. There are no excuses! It would be wise of you to get rid of your best friend and tell your husband to go stay somewhere else for a few weeks so you have time to yourself to decide whether you want him around or not. This will also give him some time to think and hopefully he will have learned something by cheating on you and you can save the marriage. If you decide to stay together he will have to work hard at gaining your trust again and be sure you let him know that.
Don't tell her she is not your friend anymore that will just be easier for her to hit on him tell her he is not interested
