Have I been too drastic and killed this Buddleia?

Unlikely. They're pretty tough IME.

Three weeks isn't that long for new buds to start to break. Give it a
couple more months and I reckon it'll be up to 4ft and looking very
healthy.

Even if it doesn't do very much this year leave it 'till the end of
next year or even the year after before giving up on it. May be give
the remains a *gentle* tug in the spring and autumn. If it doesn't
very easily pull out it ain't dead.
