I would probably reply to that with something around the lines of:Too late, when I downloaded it I thought he was asking for help so said "Yes it downloaded but some of the grammar needs sorting out".
He said he was happy with the grammar
"While you may be happy with how it looks, an employer isn't going to be happy with it. If you seriously want a job, then I can help you make it look more like what current employers would want to see."
Would his partner be happy with you showing him the CV you worked on with them as an example of what might look better?
