Assalamu alaykum i am a Muslim sisterly advice to you, i don't know how you were raise up as a muslim woman but we both know and acknowledge that MUSLIM WOMAN ARE NOT allowed to marry Non-Muslim man that is clearly mention in the Qu'ran and Sunnah (prophetic saying) of Prophet Muhammad peace be upon him. If we woman are not allowed to marry non-muslim man let alone to have kids. Inna lillaahi wa inna ilayhi rajaoun (To Him we belong to Him we shall return). I think you should go visit your nearby local masajid for this issue i am wondering if you were married in the church or in your local municipal court because imam at the masajid usually advises the sisters who wants to get married to a non-muslim man.
