I think love in all of its wonderful forms IS a choice, but, unfortunately, I don't think 'chemistry' is (if it's not there initially or once it's gone). Fortunately, there are many more kinds of love than that (often) short-lived, 'in-love' feeling. At least that's been my experience. Good question!
