We will certainly pray for you!
I'm a little concerned though. You spend the entire past listing worries about the future and than ended with a question about his past. Are you perhaps worrying about his past, to keep from thinking about your future?
I have to ask, but what if he never becomes a Christian? Aren't you worried about being "one eternally" who does not share you values (respecting and sharing are not the same thing) and does not worship your God?
I know that once you have given your heart to someone you don't want to think that they are not the one you are going to be with forever. There isn't a woman alive who didn't want to marry the first man they loved. It's wonderful to be cherished and if you give it up, you worry that it may never come along again. Believe me, if you give your heart to God, He will find someone worthy of it.
God Bless,
GRACE
