What is the ruling regarding my remaining with my Tunisian wife, whose virginity I doubt, especially since I have a child with her, I do not feel enjoyment with her, I discovered that her brother drinks alcohol, and she lives with me in Egypt, far from her family?

The fundamental principle concerning a Muslim is their soundness and the presumption of good faith towards them. A husband's doubt about his wife due to the disappearance of the hymen is misplaced, as it can be lost for reasons other than intercourse, as Sheikh Ibn 'Uthaymeen mentioned. One must cut off obsessive thoughts and not allow Satan room to corrupt marital life and break up the family, especially with the presence of a child, as this contradicts the objectives of Islamic law regarding marriage, which are tranquility, affection, and mercy. The husband must keep his wife and treat her well, and repent for having exposed her to a doctor to examine her virginity; this is not his right. By repelling such thoughts, feelings of dissatisfaction and unhappiness in marital life may be dispelled.
