Advice: Non Jewish Children / Jewish Father
Question
Answer
Shalom!
Thank you for your question and thank you for being so straightforward and honest.
You are not Jewish nor are your children.
There is also no reason for you to convert. Indeed, a conversion for the sake of marriage is almost always invalid. So too, it is not possible to convert children who are either living with a non-Jewish mother or a non-observant Jewish father.
As an orthodox rabbi, I cannot, of course, condone any form of intermarriage, and as you now know, the children born from a non-Jewish mother won't be considered Jewish according to Jewish law. Furthermore, almost all intermarriages end in divorce, especially after children come into the picture. Save yourself the heartache: the dual identity is impractical, and will, in fact, be a disaster.
Therefore, I recommend you put your current relationship on hold and hopefully your children can have a nice relationship with their Jewish father and grandparents.
