Dating a non-reader: YES - my previous boyfriends were non-readers, and we had other things in common, like sports or outdoors and...chemistry *ahem*, so that was OK. However, they were never a part of my reading life, which is a bit part of my life actually. But dating and going out with them is fine - as there is a line drawn in the degree of intimacy.
Having a non-reader as a soulmate and life-partner: NO. I hate double standards, but I am guilty of that here
My soulmate and life-partner is someone who shares every aspect of my life, and if he's not a reader, he will never totally understand me. I'm glad to say that my current partner, reads and thinks more indepth than me, and it's always awe-inspiring when getting into a book discussion with him (it always veers into lots of thought-provoking areas which I would never have been capable of doing so on my own).
