Not really, the kid was giving her something she thought she needed or was not getting. If she just wanted sex, she could have found many adult males willing to do that.
What I find so surprising about many of these teachers is, it's one thing to risk your marriage and the thought of divorce, but totally different when you add you may end up going to jail, you are on the pervert list for the next decade, lose the job you trained for and everywhere you go, people are going to nudge one another and look at you. This is about as low as an educator can get, and I hope she gets a nice long prison term to remind her and be an example of what educators should not do, no matter how much you think you will get away with it.
