What will you do if you know your partner is cheating ?

I confronted him and suggested for counselling. I cannot be the one who is giving in and make the marriages work. I waited for a year, its nothing has improve or changed. I have decided to end this marriages as there is no meaning. I move on with my child, i tell myself why should i keep this marriage because of kids. My ans is as a single mother, we can raised a child without a man.
