I am so glad to see these laws on the books.
In the stone age when I went to school, 2 different male teachers began dating female students immediately after the students graduated.
For those of us who were seniors the next year and had these men as teachers, the ick factor was through the roof.
Oh and the “relationships” were pretty short-lived. I feel bad for the young ladies involved, and I certainly wonder what kind of “attention” they may have been paid as minor students.
OP, I’m sure your former teacher is lovely, but there are lots of lovely women out there. Go look for them.
