Only the puritans (a minority group) are against reading the Bible. The Qur’an does not forbid it. I have a number of versions, my favourite being the Jerusalem.
There is no reason why a Christian should read the Qur’an (apart from a desire for knowledge). The Bible - and the teachings of the Church - are more than enough.
I realise that potential marriage is not the issue here; but be advised that while a Muslim man may marry a Christian (or Jewish) woman, she is under no obligation to convert to Islam, and has every right to continue practising her Faith. My wife, for example, is a Catholic. And no…she has never read the Qur’an!
