Please help me understand this repeating dream.?

I don't know why you guys can't be togheter, but I'm guessing religion. I can safely say that because you mentionned the bright room (spiritual) as well as the nursing mother (i.e. mary and christ). The kids in your dreams could b yours, that would me you have deep interest for that girl. I can't tell you how to run your life, but if I were you, I'd screw the beliefs and get with this girl. She might be the one, according to your dream.
