Ok it happened. We are in front of a fact and no kind of criticism undoes what has been done. You betrayed someone who matters to you and at the same time, you are not ready to lose. Now you have to decide if you will tell him or if you will live with the feeling of guilt. If so, is there a way to tell the partner you cheated on? How do such conversations start?
Think about why it was done
You may be feeling very bad about what you did, you may have been drunk one night, but think clearly. People are complex and consequently their actions, but this kind of argument is not enough. You need to spend enough time with yourself to understand why it happened. Once you have understood and faced your facts, go before him / her.
Sure his / her first question will be "why done". Are you ready to answer honestly? Avoid excuses and see the whole situation from the partner's point of view.
Reassure yourself that you will have this conversation
Every connection is different. Only you, as the parent can know for sure, how this will affect your partner. Sure, you should have thought about it earlier, but still share with yourself why you are going to have this conversation. Will you eventually separate from him / her? Do you feel guilty enough to keep it in your conscience or will you give the report a second chance? It is very important that the mistake is understood by you and not by someone else. That would make things worse.
TALK
Once you have clarified the above things talk to yourself with your partner being direct and careful at the same time. Apologize, give reasons and tell everything, but at no time blame your partner for your action even if you have any dissatisfaction with him / her. Give them time to ask the questions they want and get angry with you.
Plan for the future
Acknowledging what happened is a step, but working together to strengthen the relationship is the hardest and most important part. Once you have this conversation, continue the dialogue about what comes next. Tell how you felt and what you would like to do next. Ask your partner what you think is best for the continuity of the relationship and above all, take care not to lose trust at any point. Take responsibility and hope the other person is in line with your expectations.
