Awww, it is heartbreaking when that happens. I've accidentally kicked or stepped on my kitty a ton of times - he's a highly camouflaged tabby that blends perfectly with my persian carpets. I'm starting to think he puts himself in my path on purpose for the doting sympathy he gets afterwards.
It may take a little longer for Albertine to come around given her skittish nature, but I'm certain that eventually she will. Does she have any treats that she really loves? Canned salmon? Temptations? Pieces of fresh meat? Have your husband lie on the ground and offer her some treats, while talking softly to her. Try doing that several times a day.
Also, play therapy can be really helpful. If you have a fishing rod or wand toy, or even just some string with a crumpled ball of paper on the end, get hubby to gently play with her (no sudden movements).
And lots of patience!
