Am I wrong for feeling this way???

Ok ladies i need some advice, my father in law and mother in law have been fighting and my father in law is tired of her crap hes talking about moving out, my husband is the oldest of 2 boys which they both have their families. My husband was talking to me this am and said if his dad does separate from his mom, he doesnt want to leave her alone or lose the house he grew up in and i understand that but i dont want to move into that house, i feel that it is his parents house and wether its in our name or not it will always be their house and she will want things her way. Am i wrong in thinking this, should i just shut my mouth and deal with it?
