"Change of faith" could be influenced either by, (a) the Guy/Gal you would be marrying, or (b) by the would-be In-Laws.

This is quite an absurd question...
If you're the religion you are because you believe it (i'd presume you have reason for your beliefs other than, "it's convenient")
So why the hell would you change your religion on a whim unless you don't really believe it to begin with. For example, i'm christian, if my girl were muslim i wouldn't suddenly not think muhammad made islam up as a means of military conquest.0THIS IS NOT RELEVANT ANYMORE

I'm open to being with someone who is religious however I cannot imagine ever becoming religious myself. I used to believe in that stuff as a young child because that was how I was raised but as I got older, I realised that actually, I don't believe in any of that, I just followed what my parents said, y'know? Maturing and getting my own mind made me more confident in my atheism, though of course, I can never 100% say god exists, I can just say that I personally am very doubtful of it. So yeah, I am happy to date and marry someone who does believe, but I don't think I will ever become religious again.2THIS IS NOT RELEVANT ANYMORE
