Why!?

So like this is the 4th time these girls from this church have randomly come up to me and invited me to a 20 minute bible study. Just talking about God casually and reading a scripture. And I always kindly lead the conversation elsewhere and talk to them for 2 minutes about a part of my life...and they then ask again. And I'm so repelled by it. And I wonder why. I always leave them with a maybe- 4 time already and not once have I gone. And I just don't get why it's so...impossible for me to want to go and somewhat be offended by the idea of it. And I'm guilty for it too. I have this...awkward distance with religion. And I just don't get it.
