I wont insist on them having a different religion, afterall, i'll be converting because i love her, if i love her i wouldn't never impose her to convert or to raise our kids on another religion different from Islam, but they'll be free to read about all in the web or at TV.
I think everybody has their own beliefs, just that love sacrifices, when you truelly love someone, please God/Allah just don't break any of his commitments related to love.

Only God Can Judge Me
الله فقط يمكنه محاكمتي

I am you and you are me, if you love i love, if you suffer i suffer
أنا أنت, و أنت أنا, إذا أحببت نفسك أحببت نفسي, إذا عانيتَ عانيتُ
