Is my insistence on marrying my colleague, whom my family had previously rejected — and who is now married with children, is suffering from marital problems, and wishes to marry me without divorcing his current wife because she has no shelter — considered disobedience to my parents and a sin on my part?

"Relationship with a foreign man over the phone is forbidden, and it may indirectly cause disruption in his home. Therefore, this relationship must be severed immediately. We do not advise you to marry him while your parents object, because obeying them is obligatory. However, if he is a man of good character and religious commitment, there is no impediment to marrying him despite their objection, for a woman has the right to marry whomever she wishes if he is suitable."
