Walk Away Wife - My Sitch

[bhopeful]

I need some advice. Here's what's going on.
My WAWs birthday is tomorrow. I've already established with her that I won't be seeing her on her birthday and I only got a maybe this weekend for an answer to taking her out to dinner. I'm still waiting to hear from her on that. So, here's my two questions:

1. I want to contact her tomorrow and tell her happy birthday. Do I email her or call her? I think that I should call as email isn't very personable, but then if I email she won't feel pressured as much to respond. When I do contact her should it be first thing in the morning or later in the day? Our old ritual was for me to wake her up in the morning by singing happy birthday and then give her all of her gifts while she was still in bed. That's not going to happen this year, so I'm wondering what to do.

2. When I contact her to wish her a happy birthday, should I bring up taking her out again? I don't want to seem pushy, but I also think that she might find it weird to tell me when I can take her out. I don't know.

Any thoughts?
