Welcome FeatheryGlow
Sorry, but I don't know either.
After reading the first part of your post, I thought that you should approach him.
But when I read on, and saw that you did, and how it worked out, I became mystified.
Carl could be right.
Justin could be right.
Why don't you just e-mail him and ask him exactly how he feels, since the semester is ending and you'd like to know where you stand ~ that you would prefer it if he said 'no' and meant it rather than 'yes' and didn't. Obviously you would word it a bit more politely than that, but you know what I mean
Good luck!
