You have to tell your partner. It is totally unfair that you asked him that question with the consequences already known. Nine times out of 10, I think partners become very happy about the pregnancy even though now isn't the "perfect" time. Did you try to become pregnant without your partner knowing? If so, that is even more unfair on your part. I am questioning your antics because you are posting to the Fertility forum and not the pregnancy forums, which immediately made me think that you are trying to get pregnant without your partner knowing...
