I am married for 9 years and we have 2 daughters from this marriage. My wife had an affair with another guy few months back. I work in a highly demanding job and I am usually under lot of pressure. There were some misunderstanding between us and at this time she fell in love with another guy. One day, she met him at one of his friends house and they kissed each other. Later, she regretted that and didn't continue with that relationship. Now, she has completely forgotten about that and is no more in touch with that person. Somehow, it keeps haunting me and I keep on imagining how she must have kissed him. I don't know what to do now as I am completely confused..I am not sure if I should continue with this marriage or just separate...what shud I do?
