I don't know if I should break up with my boyfriend?

I have been with my boyfriend for 1.5 yrs. We love each other beyond belief and although we don't always agree, we tend to get along really well. Lately though, my mind has been wandering. There are two huge factors that lead me to believe we have no future together. First off, I am loyal born again Christian and he is agnostic. He also does not respect the fact that I worship God. Secondly, he hates children and never want s to have any. I would like at least 1 and he isn't willing to compromise with that. I wouldn't be thinking about any of this so soon in the relationship, but he wants a vasectomy by the end of the summer! We had a huge talk last night and again today. I think we are broken up, but I'm not sure if it is the right thing to do. I love him so much...
