Why did Judy Garland divorce Vincent?

Answer 1

Oh, dude, Judy Garland divorced Vincent because their marriage wasn't exactly a walk in the park. It's like, they just weren't vibing anymore, you know? Sometimes things just don't work out, and that's totally fine. Like, relationships can be a real rollercoaster, man.

Answer 2

To the very best of my research on both Garland and Minelli, the reason for the divorce was Judy's mood swings (unpredictable behavior) because of the pills she was taking. Vincent couldn't deal with it, and it was decided that Judy be the one to actually file for divorce for public image sake. A direct quote from Judy Garland:

"Vincente and I have come to the realization that we're happier apart. I'm sorry to say that, but it's true. We tried very hard to overcome the difficulties of incompatibility. But it just won't work."
