When I was in JSS and SSS in Ghana, I knew more than three people (students) who were in romantic relationships with teachers—and though it was not really out there for everyone to know, it was not really a secret too.
I did not think anything of these relationships between my classmates and teachers—and I didn’t even think it was wrong for a teacher to be dating a student until I travelled to USA.
Out here, it is against standard rules in many institutions for teachers to be sleeping with students/pupils—let alone, hold long lasting romantic relationships.
I have heard of several teachers who have been banned from teaching forever for having affair with their students/pupils—and it is not that these students were under age or anything, it is plainly not allowed no matter the age.
