סכין בשרי לחיתוך לחם

Helo, it is a big problem. touching or having a relationship with a goya is worse then touching a nida. one os not supposed to have any relations with none jewish girl. but more then that- if the beith din will discover that you have relations and that she supposed to mary you after the convert, they aill have great problem to convert her, since you can convert "a woman for a man" and vice versa. you"l have to wait, and to make your best to speed up the convert.
