Craigslist roommate love :(

I'm in love with my roommate who only just loves me as a best friend and roommate, we have hooked up a lot, and he has befriended all of my friends. I hate when he is around my friends without me. Can someone articulate this feeling? It's not really jealousy, because he's not mine to have and my friends aren't threats to my complicated relationship with him. This feeling makes me more nauseous than anything I've felt before though and I need to make it stop. Is moving out my only option?
