So I had to go back and delete the scene I'd been stuck on and attempt a re-write. Then that still didn't work, so I went back and deleted the whole chapter. I had to put some serious thought into the love-scene lead in and decide what I really wanted to reveal about my characters in this scene.
After tossing around some ideas, I found the right way to go about it and just as I'd hoped, everything flowed from there. I've done 5000 words in the past few days and am now getting into the second half of the book and heading toward the story climax. Exciting times!
