advice please! unfair school punishment-assumed sexual offenses
Let me start off by saying I am not a parent. I am sixteen years old, and I need some advice. I'd also like to start off by saying that I am a very good girl, have never gotten even so much as a detention, am in all honors and AP classes, and make straight A's and B's. Two days ago, after school, I had a little bit of free time before my PSAT class. So I met up with my boyfriend and parked in a parking garage next to the school to just hang out until my class. We decided to sit in the back seat instead of the front, which I know was stupid mistake number one. Then we decided to like recline in the back seat, which was stupid mistake number two. My boyfriend had his jeans off, but he had shorts on, not boxers, actual basketball shorts. I know that sounds pretty shady but there wasn't a sexual reason that he took off his pants. He was just getting more comfortable. So we were kind of just laying there and kissing on and off when these two teachers (two of his football coaches) approached the car. They were basically just like, you guys need to leave, and we did.
The next day at school, we both got called down to our own dean of discipline. I'm not sure exactly what went on with my boyfriend and his dean, but I'm sure it was similar to what I was enduring. My dean of discipline told me that the two teachers saw that my pants were down, and that when we saw them coming over, my boyfriend quickly grabbed his pants and then shielded me so I could pull my pants up. First of all, my pants were not down. Second of all, I know he did not grab for his pants because he had no reason to. He was already appropriately covered, and I specifically remember that whole event. He never grabbed his pants. He didn't even touch his pants until after we left the garage. But now all these adults, who I've never even met in my life so they don't know me at all, assume that more was going on and now we've both been suspended for three days. And they said that the reason that the punishment is so bad is because they think that we were lying. I sat in my dean of discipline's office for over two hours because she was trying to get me to say that we were doing more than just kissing. I insisted over and over again that nothing more happened, but now all the deans think I'm a liar, and I don't know what to do. My parents also think I'm lying, which absolutely shocks me because I thought of all people, they'd support me. I'm a Christian, so of course I believe in abstinence until marriage. I even go to a youth group every sunday, and camp in the summer. So now I feel like I have no one to turn to since my parents are a lost cause. I talked to my best friend's mom, and she suggested that I talk to a school counselor. I will probably end up doing that, but I was wondering if anyone has any advice on what to say in the email that I send the school counselor, or any suggestions of other actions I should take. Please help me out. I'm really grateful for any help. Thanks!
