Everyone has different coping skills. so one has to see pros and cons of a situation before deciding what to do- your spouse s personality, your personality, family support etc all these factors need to be considered. In addition your basic relationship counts too. What is it like? Many people are monogamous but many are not. If he is openly cheating on you and deliberately hurting you, you need to weigh options because often a bad relationship leaves more scars on the children as well. Sometimes than living separately and seeing the mother happy maybe better for the children than seeing her unhappy in a bad marriage. But like I said other factors need to be considered too so do talk to someone.

It's time to have a face to face conversation with your spouse. What things are making you helps less ??? And what is it that you want to make decision on.
