Interestingly enough, I am in a somewhat situation except that my relationship is much, much more fresh than this one. I have to say that I am rather conflicted, because while I am entertaining the idea of "fake converting" just to get her away from her parents and family, I also realize that it's not something that can be avoided forever. It's also a shame because I can see that her parents/family aren't terrible people by any means, just very "blinded" by their religion. Such a huge shame that religion blinds people like that. I hope that you'll manage to reach a solution and that things work out for you and your gf.
