Or at least that was my understanding of it If you haven't already, you might want to consider sitting the relevant people down and explaining your perspective. Its the same reason doctors, nurses and psychiatrists can't date their patients. I don't want to go into too much detail as we don't want to be recognised but we're both consenting adults. It's the teacher-student thing that's believed to be the problem. Hence it is guided by a code of ethics which may however vary from one society and country to another.
If they're not your teacher anymore:
What do you think of teachers dating former students?
Junior year came, and the weird talk about feelings came, etc, etc, etc. The teacher takes steps to maintain professionalism in the classroom, which may entail holding off the relationship until the class is finished, getting the student transferred to another class, or recusing themselves from the class and finding another teacher, depending on the stakes of the class in question. Since in the case of age gaps society tends to view money as the cause for marriage and not love. I don't want to go into too much detail as we don't want to be recognised but we're both consenting adults. Well, that's definitely not the norm, though it's not "wrong" either.
