First, do you have a non-thesis option? I'm just finishing grad school, and practically no one goes in with the same plan as they finish. I was going to do a thesis until one of my profs said that it really wasn't necessary unless I was doing a creative thesis, and was getting an MA with an emphasis on creative writing or poetry, for example). Otherwise, he'd prefer that I continue with classes and have a more well-rounded education. He was right about that.

Anyway, you're a grown-up person. Go and talk to the other members of your thesis committee and see what they have to offer. I'm certain this isn't the first time the problem has arisen. All of my advisors have kept our conversations private, and I'm certain yours would do the same.
