SR, I think that the birthday thing would be mostly for your dd, not for your W. I don't think you want to give the impression that it's about your desire to celebrate her birthday...that would be pursuing.
I think some chit chat and friendliness is OK, but never taking it further than she is. And not predictable or reliable on your part.
