I would say, kids are not ready for an opinion, leave them out of the decision making process. Change is fearful for most unless something is pushing them to do something about a situation. Only one who is uncomfortable about this situation is you. Others will try to convince you to suffer. You need to take a stand. If your hubby is having hard time in his office among colleagues and his team, he will look for another option. Will he listen if you say, the kids want to stay here, I like it here, please put up with your office.
