SUBREDDIT: r/relationships
TITLE: Me [28F] I have a long term relationship with [27M], but I think I am falling hard for one of my teachers.
POST: We have been together for 2 years and living together for the last year. It's a good relationship, he loves me very much and is very kind. I have had passionate crazy relationships in the past so I thought he would be the "best" guy to settle with. Everyone (friends, family) think he is adorable and so good to me but I feel like something is missing.

I didn't realize how much I miss passion in my relationship until I met my french teacher (3 months ago). He instantly light up the room for me and I couldn't stop staring into his eyes. I have been obsessing over him ever since, think about him all the time, I see his face during sex with my boyfriend, I dream of him every other night, en so on...

I don't know how to handle all the feelings Im having. Worst part is after class is over I am going back to my hometown and probably never see him again. The only thing I do know for sure is he likes me too, I see it in his eyes and in the way he get's nervous when I around him but he might have a girlfriend or other issues.

I am kinda desperate and have no idea how to handle the situation, any advice?
Thanks in advance so much!
TL;DR: 
I am in a good relationship, but I think I am falling in love with one of my teachers. What do I do?
