It is time for you and your husband to sit down and have a good chat. Does he know how you feel? He is not a mind reader. You have to tell him that you feel that you have a problem with his family and what the problem is. Start being yourself and let him know that if there is criticism, you expect him to defend you to his family. As his wife you have that right. Unfortunately, men are often clueless to what is going on around them. Since he doesn't have a problem with his family, he thinks no one does. Typical male thinking.
