I'd be a liar if I said it's not what I wanted. The only thing that really matters is the next thing you're writing. You've written two novels since your first collection of short stories. I'm back writing short stories right now. I love them.
Short stories are a lovely little explosion of a moment.
They can encapsulate an entire life purely by suggestion. But you have to get every word right in a short story. Ultimately, I wouldn't choose between short stories and novels. Very few people read short stories in collections, which is a bit of a problem. You tell your publisher you're working on a collection of short stories and they groan.
