My wife wants to move out of my parents house as she does not get along with my mother, but I want to stay with my parents. What should I do?

This is definitely a tough situation for you. May I ask, your reason/s for wanting to stay? If it's financial, you have to tell your wife openly your concern. Do tell her that you don't have the financial freedom just yet to be on your own. Believe me, if you talk it over to her heart-to-heart she will understand. As long as you assure her that you will find your own place as soon as you can, then she'll take it with open arms. However, if you have reasons other than money, still talk to her. Honesty and sincerity matter here. Whatever your reason is and decision will be, remember your marriage and your wife are your top priorities. Good luck. :)
