What is the jurisprudential ruling if the wife insists on not sitting down to resolve any dispute and insists on divorce, while the husband refuses that? And what are the consequences of each party's insistence, and what is the role of the wife's guardian?

We have previously clarified what you need to do. If you can compel them, there is no harm. However, if the law grants the wife the right to Khul' (divorce initiated by the wife) and you are bound by it, then it is permissible for you to accept. Do not compel someone who wishes to leave. There are many other women, so do not insist on the marriage remaining. For a problem to occur now is easier than for it to occur with the presence of children.
