Amiga, it appears to me that this part of his email cannot be fully comprehended without the rest of the text and a true understanding of the relationship and discussions you have had with this man.
You mention in a subsequent post that he is indeed a spiritual person and thus, it may not be unreasonable for him to say what he has said. It is not reasonable for a believer to review his relationship with God and make an effort to square things off with Him as he believes he should before seeking to engage in a lifetime commitment.
Perhaps he could engage you and together you can plan a spiritual development together but only if that is what works best for both parties. In any event, I hope and expect that he should be open and honest with you about all things that could affect your relationship.
All the best!
