How do I stop jealousy? It is tearing me apart inside!?

I have strong feelings for my housemate. I know that she doesn’t care for me in that way. She prefers my other housemate but he will only ever think of her as a friend. How do I overcome this jealousy. I can’t stand the two of them talking together.

You should move out. If you didn’t have to see it everyday, then you would get over it sooner.
