how long have you been together? if you're madly in love, seems to me that religion hasn't bothered you so far. do both your families know... or are you wanting to get married but can't tell them because of your different religions? i think that if you've been together long enough and truely want to commit to each other you should do what YOU want to do. you can't live your whole life through your parents and they should respect this. but it's tricky with religions...
They called us a dead generation,
They told us that we wouldn't survive
They left us alone in the maelstrom
As you can see we're all clearly alive.
