is it right girl muslim marry with non muslim boy?

Islam does not allow Muslim women to marry non-Muslim men.

A Muslim man can marry Christian and Jewish women because Islam respects these religions and prohibits the Muslim man from forcing his wife to become Muslim. But Christianity and Judaism do not recognize Islam and provide no protection for the Muslim woman from being forced to leave Islam.
