Well I'm happy to hear that your party was quite successful, how long did it take to clean up afterwards? You even wore a tuxedo...stunning...also your W's nice comment.
For your birthday, yes, take the nice gift from her as a positive - it could have been socks. Lol.
I also think she is just being cautious about the hug and kissing, but she was softer and is being that way consistently you say - those are baby steps. Have some patience (I know you do), it takes time.
