I'm in love with my teacher? Help!!?

My whole life I've been privileged since my dad is the superintendent of our school district. When I was in the 7th grade, I had a crush on a 12th grader. I knew that I didn't have a chance, but it was just one of those crushes that most girls have that they forget about.

My history class was introduced to a really handsome new student teacher. It turns out he was the same 12th grader I had a crush on.

It's been 3 months since he came and oddly, we've been really close for a student and teacher. Like I said, my dad is the superintendent of our school district, so I do go out to dinners with him & teachers. My friends, who also think he's attractive, found his #. (I know how creepy this is).

At a sleepover 2 months ago, my friends texted him with my #. After a week of feeling guilty, I told him I was the girl texting him. We didn't stop texting & last night we went out on a date. As we were leaving, I saw my principal. I know he saw us & I'm afraid he'll tell my dad. PLEASE HELP!
