For background:

My fiance and I are both currently in our student teaching semester of our Education degree. My fiance has been placed to intern with a K-4 Elementary Music teacher.

Her internship teacher has been very forward about the fact that he wanted an intern so that he wouldn't have to do his job. He immediately began giving her tasks such as being in charge of videoing the students for announcements, teaching full grades, spontaneously letting her know it's her turn to teach (all in the first week), having her fulfill duties regarding his non-academic YouTube channel. He went as far as to say "You're paying me for you to teach my class."

Some of it is good experience, if my fiance was ready for it. She has come home almost every day, beaten and mentally exhausted. Today, in week 3, she came home and informed me that her teacher told her "I don't think I'm getting my return on investment with you." She is a very nonconfrontational person so she held it in until she got home.

When I got home, she told me the story and that she almost went in to change her degree. My response was "Email Professor [in charge]". My fiance believes that it will be a waste of time and that she is going to be told to just change her major. After a bit of back and forth about her emailing a few of our professors for help, she finally blew up on me for pushing her to do something when she just wanted to vent.

Am I the asshole?
