Have you ever tried not making it a battle? My family is very, very close. When my boyfriend and I first got together, he had difficulties with my wanting to be there all the time and "putting them first." The fighting about it only made it worse - the more I felt he was putting them down the more defensive I got. I feel, and I could be wrong, that the more supportive you are of his relationship with his family, the more he will feel the need to defend you when they launch their attack. Imagine you have a son you loved, took care of and developed a friendship and mutual respect for. When he finds a girlfriend that means he has to defy you, stand up to you and never see you again just because of her? I believe a mother naturally shows her claws when she feels threatened, and really there is no need for any feelings of competition because you both play very different roles. This is my advice, and I could be wrong, but I think you finally realizing that it isn't a competition, and that you don't have to prove your value in his life to his mother will lead to a calm within yourself that can no doubt calm the entire situation. Let me know how it goes...
