@deb790,
Probably should have thought about this before getting married. Have you and your husband discussed this at all? What is stopping you from moving out of the in-law's home? Is it money? If so, do you have a plan in place to save the money in order to move out by a certain time frame?
It is my experience that a person can put up with a lot when necessity dictates it. Suck it up and put a plan in place to change the situation. And remember, your in-laws opened up their home for the two of you when they really didn't have to do so. They are having to put up with you also.
