Hello, highschool teacher here with a bit of an issue. There is a student in my class who seemed a little weird and doesn't have many friends so I befriended her by eating lunch with her sometimes and helping her with homework. I soon found that she was not weird at all but just... different. We began to hit it off and became really good friends and since we are both lesbians she usually comes to me for relationship advice. The other day she came to my class after school crying about her girlfriend cheating on her and I was so angry I shocked myself, but I was also happy in a way because she was now single. I felt horrible after feeling that way and tried to brush it off but a couple days ago we had this conversation:

Student: Sorry I forgot my board again

Me: Sometimes I think you forget that thing just to see me

Student: Yeah just to see that horrible face

Me: Haha you love my face

Student: I love more than just your face

That last comment made me blush and even turned me on a bit but I told her leave playfully so I wouldn't upset her although I was angry at her for making that comment.
There are plenty of rumours going around of me and her sleeping together and scared of losing my job or worse. The student is graduating this school year so I can wait but Im scared if these rumours are already too widespread. What do I do?
