...i let my student lead me into something i shouldn't have ...

I've been married for five years now and we both work very traditional hours. It started when this new student joined class, he was... different from the rest, somehow magnetic... We'd catch each other's eyes across the room sometimes, there were definitely feelings involved, but I pushed them aside. Then one day, he invited me to his place after hours for a 'special meeting.' It ended up being so much more than that... There are certain things in my classroom cupboard that should never be used on teachers or students... It was just... wrong... And yet, part of me wonders if I'd ever let it happen again. How does one even go about getting help with this?...
