Does divorce occur if the wife requests a divorce due to a problem between them, and the husband says: "If you want this, there is no harm if divorce occurs"?

This wording could be a promise or a response to a request for divorce. Due to its ambiguity, divorce does not occur unless the husband intends it. If he intends that he "will divorce her," this is merely a promise, and a promise of divorce does not constitute a divorce unless the husband actually executes it.
