Can I be forced to go back to school by my boss?

I work at a community college and my boss has been asking that I go back to school to get my bachelors degree. I dont need this degree for my job since it only requires a high school diploma. She is very nice in wanting to make it easy for me to go back to school but I am not interested in going back. I would like some advice as to how to let her know that I am not interested in going back and that I appreciate her willingness to help me. I dont want to hurt her feelings or have her fire me for not doing so.
