You are not looking at the most important element in this situation. That element is YOU. Children are certainly an obligation and a responsibility, but YOU are supposed to be happy. People who believe parents should sacrifice their happiness, sanity and common sense for their children are idiots.
Your special needs son is manipulating you because he probably has no concern for your needs or emotions. It is only natural for him to see only those things he himself wants. The most important thing you can teach him about life is that he will not always get what he wants. He has to learn to consider the things other people want too. That can be extremely difficult with a "special needs" child, but it is much more preferable and less stressful than living with a man who could care less about his family, his kids or you.
If you have proof of your husband's infidelity, retain a good attorney and make him pay for that sex for the rest of his life. Have your attorney sock it to him for all the alimony and child support you can get and don't look back. In the long run, you will be much happier and so will your kids.
