Qur'anic Interpretation

Does the Term Unbelievers Include the People of the Book?

Dear Scholars and all sisters/brothers, Assalamu alaykum.all Scholars agree there is no way to justify the marriage of a Muslim woman with a non-Muslim man even if the woman works and provides for herself and the husband lets her practice her faith in every aspect of her life. According to the Qur?an: "Nor marry (your girls) to unbelievers/idolaters until they believe: A man slave who believes is better than an unbeliever/idolater, even though he allures you. Unbelievers do (but) beckon you to the Fire. But Allah beckons by His Grace to the Garden (of bliss) and forgiveness, and makes His Signs clear to mankind: That they may celebrate His praise" (Al-Baqarah 2: 221). But does this verse include the People of the Book as well? It is still not clear to me if the term ?unbeliever? includes the People of the Book as it looks like in other verses there is a clear distinction. Can you please shed light on this? Also, Scholars agree a married woman that converts to Islam should leave her husband if he doesn?t convert too (even if they have kids and the husband lets her practice her faith). To me it is not clear why Allah would like a family to break up like this. Am I a sinner if I don?t agree with the Scholars especially because the Quran doesn?t mention the case of a convert? Please note I?m married to a Muslim man. I?m a convert to Islam, alhamdulilah, and although I accepted the Quran, it?s still hard to me to accept ALL Scholars? point of views: I know they are respectable Muslims that have been studying Islam all their life but they are human beings like me that can make mistakes and cannot be sure about the TRUE and UNIQUE interpretation of Allah (SWT)?s words.  Jazakum Allah khairan.
