Have you learned that your spouse is cheating on you? If you have ample evidence to suggest and prove so, then there has to be a remedial measure taken. But prior to which, you must confront him or her to ascertain the gravity of the situation and know his side of the story as well so that you can make a decision that is best for you.
When you dealing your partner, remember a few things.
Firstly, leave no room for self pity once you have known that you have been cheated on. Questions about your beauty or looks are to be laid aside because all that they will do is hamper your self esteem. It will prevent you from thinking along the right lines and that is to be avoided at all costs.
Secondly, let the idea sink in and have acceptance for the fact that this has happened. Do not make hasty decisions carried away by emotions. Do not end the relationship before hearing him out and knowing the causes for what he has done.
If your partner is known for his temper, then do not confront him alone. Always have a friend or a trusted family member when you meet him to talk it out with him. Never have a confrontation in front of your children. When you do talk to him, ensure that you keep all the evidence handy.
Having put your case forward, listen to his side of the story and analyze it. He may completely deny the affair or come up with a story that might match your knowledge. Always probe and ask more questions to ascertain what the truth is in case of an ambiguous explanation.
Bear one thing in mind; in case what you have found out is true but you still want to go ahead with the relationship and give it another try, do not let him know straight away. Give him an ultimatum and let him know that he must end the other relationship immediately or end the relationship with you. This way, you have an upper hand and if you ever find him cheating again, you will have the final say.
