@Michieh087,
Don't room with people you have crushes on.
I had three separate male roommates (I am a female-type person) way back before I got married. John, John, and Pete. Complicating matters was living with two guys named John at the same time.
They had girlfriends. I had boyfriends. So what? They did their thing and I did mine. Hell, I was friends with John #1 and Pete's girlfriends.
You are making your life hard by living with your crush. You have two choices: stop having a crush or move out. Sorry and I know that's harsh, but you are just going to keep making yourself miserable. You are this guy's roommate. He splits the cable bill with you. That is how he sees you. Period.
