Again with High School, this one is more pressing

A little while back I had dated a fellow classmate. She was...to say the least interesting. During our short relationship she had revealed that her and a certain teacher had "hooked up". Me being a normal high school senior wanted to know more, but she said I would have to wait to know when she turned 18. This I took as something sexual most likely happened. After she told me and we broke up (not because of the teacher thing for other reasons), I had always looked down on the teacher. She was kinda the 'gay-icon' at my school. She wasn't out, but she was. Everybody knew, nobody said anything. Until recently I never liked her. However, a few weeks ago I was drag on to do the graphic designs for a student art magazine in which this teacher was moderator of. During these weeks we had spent time after school, texting each other, and work well together. I began to like this teacher, not in the way that my ex-girlfriend liked her apparently, but on a really good teacher-student relationship. A few days ago after school I went to go talk about the magazine with this teacher, she wasn't in her room. I found out she left in a huff right as the bell rang. After that I texted her and asked when the magazine was going to be printed, and ended up finding she wouldn't be in school for awhile. I asked why, she said a family problem. Okay, that's all well enough. The next day I get called into the principle's office and I'm questioned about my relationship with my ex-girlfriend. On top of that I was asked if in the past few weeks, has this teacher ever made any inappropriate passes towards me. It suddenly hits me that the shit has hit the fan. This was shortly followed by, she might get fired. Which was directly followed by...this is going to turn into a "lesbian problem". It should have never happened. However, when my ex-girlfriend told me it seemed more like she was bragging about it. Like she wanted people to know and think she was cool for doing what she did with this teacher. Now, I have come understand that she has done something similar with an ex-boyfriend of her’s. After he stopped talking to her, she told her parents he was harassing her and they tried pressing charges. Her ex-boyfriend was a friend of mine and I would trust him over her, it’s just the kind of person she is. During my weeks of getting to know this teacher, she revealed she hadn’t talked to my ex-girlfriend in a while. So even though this situation was brought on by the teacher, it seems it’s being exploited either over jealousy or boredom. I am saying what this teacher did was alright, I think it was horrible for this teacher to ever think about crossing that line especially with a student who was under the age of 18. However, both being seniors and graduating in a day and half, my ex-girlfriend has kept this quiet since sophomore year. She couldn’t wait a day and half? It’s an unfortunate situation for both the teacher and my ex-girlfriend, but now students are turning on the teacher and/or the student. Even worse other students are being dragged in for questioning. These questions are embarrassing, they are awkward, and prying. What are you guys’  gals’ opinion on this? I’m just happy I’m leaving, being an outted lesbian at school I would hate going through the halls with fellow students thinking I’m pervert because of “what the lesbian teacher did to that student last year”.
