First, are you absolutely sure he did ? How badly ? How good of a friend is it ? Is it really any of your business ? Most people don't want to hear this kind of thing even if they should. He will most likely get caught on his own without you saying anything. Your friend may not believe you and you lose a friend without gaining anything. Of course, you can always ask him how it went with the other woman. Just in casual conversation with him alone. So, was (blank) any good ?
Follow your gut
Her husband has probably cheated on her more than once and any woman who is loyal to their husband and finds out they have cheated is extremely hurt and certainly will become angry, but few seek revenge. If you feel threatened by her and you know her ex then the three of you should meet and you tell her right to her face you had nothing to do with him; get up and tell the two of them to grow up and he should tell her the truth and then walk away (do this in a public place.)
Tell him honestly & as soon as possible. Don't omit information, either. You were reckless. Since you cheated, face the consequences.
He will leave & you deserve it. YOU CHEATED ON HIM. It's not fair to him to be cheated on without knowing & it's unfair for you to leave HIM because YOU cheated. Cheating, if you want to cheat then face the consequences.
Demand the truth, or tell him you're leaving him. No one deserves to be cheated on..
yes just tell him that you only want to be friends
If you truly love him and trust him then you should take his word for it. ANSWER: Well then if your husband says they are only friends, tell him next time they talk make sure that you can talk to her to. How about tell your husband that you want to invite his new friend to dinner at your house. If his face change because of what you wanted to do, then the evidence will be clear to you..
If you have proof they have cheated then confront your husband (he is mainly to blame because he is an adult and knows better) and tell him that he and your sister in law have a week to tell her husband or you will and if he does not break up the relationship with her then you are filing for divorce. You husband and sister in law have created a situation that has hurt you, her husband, any children they may have, but also hurt the rest family as a whole and cause two brothers to end a possibly good relationship.
This begs the question, "Why would you?" and perhaps, "How is it any of their business?" Supposing it was it was any of their concern however. You would simply look them in the face and say, "My husband has a child by another woman."
Are you saying you cheated while broke up? If that is the case i would say NO, dont be in a hurry to tell him, Only if it is really bugging you , then let your conscious be your guide.
The easiest way to tell someone you like them is face to face in private. If you text them or your friends tell them they will not take it seriously and if you are not in private they will react differently around their friends so make sure you are face to face and no one is around.
Tell her husband to watch his back.
