We are having major issues in our marriage where we go for weeks or months without speaking or seeing each other. In such a scenario, how can I fulfill my desires without committing a sin?
The best way to go in this situation is to try your best to reconcile and patch up. There is no question of committing a sin at all. While you are trying to reconcile, you must control your desires in every possible way including fasting which is very helpful in such situations.
Wassalam.
