What's your funny feeling about? What do you think his "I'm busted" look is about? What does your gut say?
Could it be the rental place?
I'm crossing my fingers that the rental place message opens up a new avenue for you...whatever way it comes, you're strong to handle and I know it will be easier than this phase you've been in...it's been getting hard on you.
Best, and let us know what happens. Until then, you keep trucking. If there's one thing I can say...it's your house too...stop tip-toeing around him and not talking. Talk to him and engage, if he doesn't respond, just go about happily to something else and keep talking to him. Right now, he is affecting your normal social behavior...you wouldn't be that way with another roommate would you? Be comfortable in your space. It gives him comfort too.
