It is wonderful that you are willing and able to be accepting and open about this; it is unfortunate for your boyfriend that he is not ready.
I have similar difficulties communicating with my (accepting and supportive) wife. I still have not completely gotten over my own discomfort about my crossdressing -- I have found it difficult to accept for so long now, that it is hard to quit being ashamed. Even though we like to dress as women, we are still men, and most of us do not open up easily about our feelings.
I want to throw my hat in the "don't push it" ring. I also would like to say that I don't think you should get him any "femme" gifts of any kind; if he is in a denial or shame phase, this will only push him further down the solitary road (I know, my wife gave me a femme gift last year and I ... just didn't know how to feel about it, I felt very strange -- and I didn't know how to communicate that to her without making her feel badly).
I wish you well, Chloe, and I hope things work out well for you and your boyfriend.
