Is it permissible to separate from one's wife after divorcing her twice, due to severe distress from living with her, and due to a lack of social compatibility between the spouses?

One must prioritize parental consent over marrying a specific woman if there is a conflict. However, after marriage, one is not obligated to divorce a righteous wife even if the parents request it. Instead, one should strive to convince their family and supplicate to Allah to reconcile hearts. If the wife is unrighteous and there is no hope of her rectitude, then it is better to divorce her, especially if she causes the severing of kinship ties. This is unless there are children whose well-being is feared to be jeopardized, in which case keeping her would be more important, out of concern for their welfare.
