md_ocr, As far as the differences you are having, have you tried meeting him half way? Or is some of his behavior things you can not tolerate or will not settle for? If so, I would reconsider. But once you are married there is not turning back. I think it is normal to get nervous. I just think I have a different thinking about relationships. I can see myself totally without FI, I can see myself single, but my FI and I together have become such a strong entity, yet we are still individual and he has made me such a better individual at that. So in my opinion, if you think you are a better person because of him then I say not to worry!
