When I was in high school, my cheerleading coach was dating the boys' basketball coach. They were both full time faculty members. We caught on quickly to their romance and teased them mercilessly. It was really no big deal, but we were fourteen and had no real love lives of our own and had to live vicariously through the two of them. My coach got a better job the next year and for the money.
There were several flings among the faculty and no one really seemed to care. One of the teachers was extremely open about the fact that she was carrying a baby that was not her husband's.

He was also a teacher there. That's was a little too open.
As long as you remain respectful about your relationship, I don't see any problem. I don't think that it would cause any interference with your students' educational process. Actually, when you're in the eighth grade, a particle of dust can interfere with the educational process. So, don't think that your private life is the hindrance that's keeping some kids from learning. If they're not learning, it's probably because they don't want to.
