Asking him if I've ever made him uncomfortable or not is a very bad idea and I will not be doing it.

Even my mom said so, and her reasoning makes total sense.

I cannot rely on him to make me feel better, or relieve me of the responsibility of having to worry about overstepping.  It is selfish.  It is so unbelievably selfish and I can't believe I ever thought of it.  It would put him in such an uncomfortable position to reinvolve him in this manner or talk to him about anything that's not academic and is related to our personal student teacher relationship.  Because it doesn't matter.  It's my problem.  I have to deal with it.  If I overstep, it's my fault, and If he doesn't want to confront me I shouldn't make him. 

I'll just do the practice interview, and then the regular one, and I'll spend the rest of the days until I graduate picking apart everything I do because that's how it has to be.

Then I can graduate, and I might think about it for a bit afterwards, but he'll be rid of me for good and that's really all I want is just for him to be happy and not have to deal with me anymore.
