Primer: My college roommate is gay and i am not. I am a male as is he. I am very open and have 0 problem with his orientation. He was my roommate last year as well and he has made several sacrifices for me and always been extremely nice. We have got along very well. Now: I come into my room and find him with another guy and they are obviously romantically interested. I leave and later come back to an empty room that is about 15 degrees more hot and smells of body odor. They obviously had sex. Later they both come back and stay there the entire night, including spending the night. The guy is back again and has been here all day. I am not homophobic yet i feel very uneasy. Me: I suffer from OCD, and losing control of my own room is making it very very very much worse. I almost feel depressed. What to do: Talk to him? that is what everyone tells me. But what can i say? he cannot be here that often, he can't spend the night? It is hard to when my roommate has made so many concessions to me in the past yet i feel that i will go crazy if this continues. any help or words of encouragement are greatly appreciated.
