I refer to Norlinda's letter If you love your partner, you'll convert.
I would like to ask Norlinda a hypothetical question - if she happens to love a Christian and wants to marry him, would she ask him to convert to Muslim first before marrying him? Conversely, if her beloved boyfriend asks her to convert to Christianity first before marrying him, would she do so to prove that she really loves him?
It can be quite a difficult decision to make for either side. Why not just be what you are and marry? After all, there is one 'religion' which encompasses all religions, and that is the religion of love.
