I wouldnt get rid of her just because she wants you to go to church. From what Ive noticed is that girls that go to church tend to be better for you in the long run. They will generally treat you better and not be as tempted to cheat and whatnot. If you are looking for a person to be with the rest of your life they generally tend to be the ones. They of course are still people so they have their faults. Honestly spending that hour sitting on your butt is not all that bad. Ive gone to church alot and I can understand why you dont really want to go though. Honestly if it pleases her parents it wouldnt hurt to do it because if this relationship lasts the last thing you want is to hate her parents because that will make everything awkward when you have to see them.
