Kerry, for W's birthday, I'd say, get her a card, and maybe a simple inexpensive gift. Something you would give a friend.
I definitely agree with you on the trip to Vegas. Also I think jewelry is probably too much. Maybe a book or a puzzle or something like that, not too personal.
Kerry, I know it will be hard going through the weekend thinking about the birthday celebration she is having without you. I know that is hard. But, ... keep it cool. Stay patient. Think long term. You have regular communication, which is good. You have a future to think about! Don't get anxious about this week - think long term.
