I think it's entirely his decision to take medication for it. There are a lot of those with anxiety disorders out there (or depression, or lots of other types of similar issues) who don't believe in medication as long as they're still able to function and aren't hurting themselves or anybody else. I'm one of them -- I think that America is overmedicated as it is and there's no reason that everybody should conform to a set standard of "anxiety level." Some level of variation in how much anxiety we all have should be standard -- why should everybody have to be like everybody else?

That said, if his decision is not to be on medication, he still needs to deal with the consequences, and not use the disorder as a crutch. If he's not going to make an effort to fix the ways his anxiety is affecting your relationship, it's probably good that you're getting out of it this early -- it'll spare you a lot of pain and trouble in the long run.
