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.
It might be that you are referring to the saying of the Prophet : "I am free from any Muslim who resides among the polytheists [non-Muslims]." [Abu Daawood and At-Tirmithi] This narration is authentic and the scholars understood it to apply on those who are not safe about their religion because the ruling of residing in a non-Muslim country differs according to the circumstances of different people and countries. For more benefit, please refer to Fatwa 86405.
The ruling on you and your family who reside in that country should be based on these details, but there is no doubt that if a Muslim can live in a Muslim country where Islam is predominant then this is better. There is no comparison between a Muslim country where some non-Muslims live and a non-Muslim country where some Muslims live.
Hence, it is more appropriate to seek the help of your trustworthy relatives or female friends so that they would help you find a pious husband with whom you can live in your Muslim country or any other Muslim country where you may find a righteous environment and where your children will be raised upon Islamic creed and good moral principles.
