Must a husband compel his wife to communicate with his mother, and is this incumbent upon the wife without her husband's command, and what is the advice in this situation?

The wife's upholding of ties with her husband's mother is a matter of noble character, not an obligation. You should encourage your wife to foster familiarity and companionship with people, and you can seek assistance from psychologists for this. As for you, you must honor your mother and maintain ties with her, and try to explain your wife's excuse to her.
