Is this betrayal- mother in law issues!!?

I'm sorry but there is no way around it. your husband has got to tell them that you are his wife and it doesn't matter if they love you or not because he does. If he can't stick up for you and have your back like a partner in life should then it may be time to give the relationship a rest. It may take a while of you living somewhere else but i think he will work up the guts to do it when he realizes that's what he's going to have to do to get you back. Good Luck!
