Muslim women marrying non-muslim Men

Re: Muslim women marrying non-muslim Men

I was listenign to a Radio Programme on VOA on this issue, where they invited a muslim female who married a Hindu. And she was saying that she doesn’t want any other muslim woman to do it, but thinks it was right for her to do it.

What i was confused about is that, people only end up getting married when they have considered another person as potential spouse. In case of a non-muslim how can a muslim consider him as “possible” spouse.
