What is the ruling on deceiving one's mother by claiming to be traveling to complete higher education, in order to avoid problems with one's wife, only for the mother to discover the deception and supplicate against him?

Giving both the wife and the mother their due rights is not an injustice to either party. The wife has the right to an independent dwelling. Strive to obey your mother and please her, and explain to her the reason for your actions, assuring her that you are mindful of her feelings. Show her your love by caring for her and sending her gifts. The wife should help her husband obey his mother, visit her, and treat her kindly with words and gifts, to remove any misunderstanding.
