It's kinda hard to see how much is still holding together in that pic. I lst pretty aggressively and I'm usually pretty impressed with how well the ladies bounce back. I would use a twist tie to hold it together as best as you can, veg for a extra week of two at the most and carry on with life. It will either heal up and flower happily or that branch will die and dry up. If the latter happens just cut off the offending branch and the rest of your girl will flower just fine.
