Oh man, so sorry to hear that. A bit of time has gone by since your original post so you may have decided what to do already but if not, I would let the end of the broken branch callous over & then pot it up in a super well draining small rooting container (cut off water bottle, Gatorade bottle, etc with holes in the bottom) and keep the bottom warm. If the plant has enough energy it may still bloom for you, if the plant just isn't doing it or looks like it's shriveling or anything then I would recommend cutting off the inflo. It's at least worth a shot! Let us know how it goes!

Edited to add: Also, it helps reduce transpiration while rooting to cut off all but about the top 3-4 leaves too.

Second that. I don't like to wait. Either it roots or it doesn't. You could take all the leaves off too.
