My Straight Roommate Seems to Like Me

My straight roommate seems to like me, what should I do? Waiting online. As the title says, I am gay, and my roommate is probably a straight man, with good looks like a school boy. He is very nice to me. He is usually flirtatious, always calling me his little wife, or crawling into my bed. I can't help but feel blushing and weak in the legs due to his teasing, but the problem is! He is straight... So what should I do, please help. Conception:
