I just mentioned this in another thread, but I kept the hugging up for a while after BD but W would bang me on the back like some creepy uncle she didn't like (before BD when we hugged there was none of the back-patting stuff). So I finally just completely quit hugging her. Basically we had zero physical contact for months. Then after those 3 months or so, whenever we would part she would move in close like she was going to hug me, but she'd stop short and I made no effort to meet her halfway. This went on for a couple of weeks and then she started coming all the way in for hugs and has been ever since. They're more like the warm pre-BD hugs than those goofy slap-on-the-back hugs I was getting too. At some point after the hugs she started kissing on the lips too. This actually surprised me because as cold as she had been for so many months I really didn't think we'd ever be hugging/ kissing again. You just never know. Give them time and space and let them make the move!
