All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
You mentioned a number of misbehaviors on the part of your wife. If this is true, then every part of what you have mentioned is sufficient evidence of her recalcitrance (Nushooz). Please refer to Fatwa 85402 about the prescribed way to deal with a recalcitrant wife.
If you believe your wife will most likely not act rightly, then it is better for you to leave her, especially since you have no children yet, and divorce in that case is less serious than it would be after having children. Divorce may be the best solution for spouses when their marriage is intolerable and no other solution can be reached as explained in Fatwa 241252.
We would like to highlight the following points:
First, it is permissible to marry a woman from the People of the Book (Christian or Jew) as a rule if such a woman is chaste. However, some scholars held that it is disliked due to several considerations, some of which were underlined in Fataawa 84724 and 88451.
Second, the preferred scholarly opinion about the wife's duty to serve the husband is that it is decided according to the common practice of a given society. Please refer to Fatwa 86344.
Allaah Knows best.
