You have, without a doubt, left him WANTING MORE OF YOU!!!
Kuddos to you for the interactions with BMF, the goal you had in mind was a huge success, I am sure BMF will have a convo with XH (if not already) very soon.
It was so nice for X-MIL to have such a lovely birthday party and XH has you to thank for making it a wonderful occasion for her.
XH apparently has a big interest in photos, you can definitely use this topic to your advantage down the road. It is so huge that he enjoys you being in them and the fact that you took many of his favorites. In a MLC state of mind, photos are one of the first things they purge themselves from for a variety of reasons: one being memories they are trying desperately to run from and another revolves around the OW's dislike for seeing us in anything involving......"Her Man".
Gosh this is so exciting....You are doing everything right. Time and patience and slow and steady. I, too, like your idea of pulling back and let XH make the next move. I think you will hear from him very soon.
I am so happy for you today
