I have been dumped 4 times by my girlfriend (at least) because I wasn't christian. That was when we were just getting started; it's tough going at first, you have to learn alot of boundaries and you gotta sort some stuff out, but in the end if you are compatible then it is what it is, right? In the end, dumping someone cause they aren't religious is silly and her friends and family were kind of bigotted, so everything settled itself out.I think the biggest problem is her parents. She did at one point say that muslims being with christians and jews was fine (And I happen to be christian but didn't mention it because I don't practise the religion in any shape or form.) She also told me after I confessed to being a bad christian that she wasn't the greatest muslim.
I had a strong feeling that her parents were a big part of it, as is the community around it. I can tell you from experience that if this girl is worth it, definately go for it. You cannot know unless you try; If you're anything like me, you'd rather be the person that tried and failed than the person that never tried at all.
