All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
First of all, we implore Allaah The Almighty to facilitate your affairs and grant you a happy marital life. You and your wife have done well by respecting your mother and trying your best not to make any mistake with her. May Allaah reward you both! For further information about the virtue of dutifulness to parents, see Fataawa 87019 and 82254. Dutifulness to one's parents is required even after marriage of the son. The son must be dutiful to them as much as he can. Here, it is useful to mention the criterion for obeying one's parents, namely, it is obligatory to obey them in what benefits them and does not entail harm on the son. We previously clarified this in Fatwa 84942.
However, we advise you to be patient with this mother and supplicate Allaah The Almighty much to correct her, to guide her to the straight path, and to grant her gentleness and kindness in dealing with you.
On the other hand, you should know that your wife has the right to an independent accommodation where she finds peace and comfort as previously clarified in Fatwa 86132. If you are able to find an independent house for her even by renting it, you should do so, it should be close to your parents' house so that you can take care of them and keep in touch with them. If it is not possible to find an independent house, then try your best to allocate a part from your father's house where you can live with your wife separately. If the two solutions are not possible, you have to be patient with your mother and be soft and tolerant with her.
Moreover, it is not incumbent on you to tell your mother about the details of your life, especially your life with your wife. Also, you are not required to give her all your money. You can save part of your money from which you buy a gift for your wife without your mother's knowledge. At the same time, you are not required to abide by the disciplines that your mother tries to control your life and the life of your wife with, and disobeying her in these matters is not considered undutifulness to her.
Finally, it is not permissible for your mother to exploit your wife or burden her with housework. Nevertheless, your wife should be patient and you should try your best to convince your mother to treat your wife kindly and alleviate her burdens. We ask Allaah The Almighty to make a way for you to get out from every difficulty.
Allaah Knows best.
