I know I am an outsider but I definitely think you should get a divorce with him. You should understand women nowadays can live without men. It is him that doesn't have the responsibility to his family. There should be no reason of cheating behind the wife. If he finds that there's a problem with the relationship with you, he should divorce with you first before he finds another woman. You should know that even if you guys get a divorce, he is still the child's father and you will still let them see each other. If you think it is no good for your child to live without a father, then you should think deeper. Will it be better to your child if you guys always fight and argue?? the answer is "NO". If your child sees you always not happy because of the father, then later on, your child will definitely hate him which will make things worst. Just remember, there is NO EXCUSE for either one party to go "boil". You can live more happy without a guy like that, or you can even find another good man that will treats you better than he does. What can be worst than your man ML with another woman. Trust me, woman doesn't need to live under tears anymore. Find ways to make your life better before you die. You deserve someone better !!! Beautiful life is waiting for you out there. Think deeply yourself. Guys like that doesn't deserve a good wife like you !!
