Wa alaykum Salam,
As soon as you become Muslim, your marriage with non-Muslim is automatically anulled. It is over. It is not recognised under Allah's law.
And an obvious consequence of a marriage with such person, is the evil and ignorance that your Christian "husband" is currently showing.
If he becomes Muslim, then there is no problem. Otherwise you must move out.
You need to make contact with a good Sunni Muslim Mosque in your area, the larger ones often have proper Imams who deal with Marriage and divorce matters. They will help you inshaAllah. They will also give you a Muslim Guardian (
Wali ). You need to think things through and get good advice from the Muslims in your community, and find a good Sunni Mosque that provides advice on this. May Allah help you dear Sister. We will make Dua for you and ask Allah that he makes things easier for you and for your children.
You must visit a Sunni Masjid that is following the Quran and the Sunnah. IN UK, London- Regents Park Mosque and Green Lane Mosque in Birmingham. These both are Qualified to settle divorce/marriage issues. In UK Please contact the Islamic Judiciary Board 0121 773 0050. They may be able to direct you to regional offices inshaAllah.
Wasalam
The Following is by by Shaykh ‘Abd al-Rahmaan al-Barraak and is from IslamQa
Praise be to Allaah.
It is not permissible for a Muslim woman to marry a kaafir (non-Muslim), whether he is Jewish, Christian or an idol-worshipper, because the man has authority over his wife, and it is not permissible for a kaafir to have authority over a Muslim woman. For Islam is the true religion and all other religions are false. Allaah says (interpretation of the meaning):
“And give not (your daughters) in marriage to Al-Mushrikoon till they believe (in Allaah Alone)” [al-Baqarah 2:221]
“And never will Allaah grant to the disbelievers a way (to triumph) over the believers” [al-Nisaa’ 4:141]
And the Prophet
(peace and blessings of Allaah be upon him) said: “Islam should prevail and should not be prevailed over.”
If a Muslim woman marries a kaafir when she knows the ruling, then she is a zaaniyah (adulteress), and her punishment is the punishment for adultery. If she was ignorant of the ruling then she is excused, but they must be separated, and there is no need for a divorce because the marriage is null and void. On this basis, the Muslim woman whom Allaah has honoured with Islam and her guardian must beware of that and must adhere to the limits set by Allaah, and they must feel proud of Islam. Allaah says (interpretation of the meaning):
“Those who take disbelievers for Awliyaa’ (protectors or helpers or friends) instead of believers, do they seek honour, power and glory with them? Verily, then to Allaah belongs all honour, power and glory” [al-Nisaa’ 4:139]
