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 is His slave and Messenger.
First of all, we ask Allaah to guide you and rectify your husband.
Islam does not approve the behavior that you mentioned in the question about your husband, and his conduct contradicts the good marital relations between the spouses that Islam recommends.
Allaah says (what means): {And live with them in kindness. For if you dislike them - perhaps you dislike a thing and Allaah makes therein much good.} [Quran 4:19]
Besides, the Prophet said, “Treat women kindly.” [Al-Bukhari and Muslim]
For more benefit, please refer to fataawa 86618 and 88304.
If a wife is greatly harmed by her husband, then she has the right to ask for a divorce. What your husband said, that you cannot be divorced until one year and one day passes, is not true. Where did he get this? [He has no Islamic evidence for this.]
Therefore, if he persists in this condition, then you have the right to take the matter to one of the Islamic Centers to remove harm off you by divorce or a Khul’ [divorce requested by the wife and in which she returns the bridal gift]. Please, refer to fatwa 89039.
It is evil of him that he threatens to take revenge on you and your family, so you can threaten that you will report him to the authorities to protect you from his evil; rather, you should actually report him if he showed any attempt to do what he threatened to do.
Finally, we say to you that we perceive from you that you are rational and have a sound mind, which we hope will lead you to that which is good. So we invite you to embrace Islam, which is the true religion, and if one holds fast to it in creed and conduct, then he will achieve happiness in this worldly life and the Hereafter.
For more benefit on the evidence that Islam is the true religion, please refer to fataawa 86091and 88906.
It should also be noted that there is a difference between the teachings of Islam and the wrong behavior of some Muslims, so one should not confuse between the two. Please, refer to fatwa 127523.
Allaah knows best.
