Awesome news!!! I'm so happy for her and I'm sure she really appreciated the flowers and sushi. Even if she didn't say it I know she did (sometimes it's hard to "connect" and show too much appreciation when you know someone wants to leave... I know I've felt that way).
Anyhow, not working can be really hard on one's emotional state and self-confidence so this should help her outlook. Try to continue being positive and supportive, regardless of whatever else is going on. It will just make the whole family unit much nicer for you, your son and her too.
There is no arriving, ever. It is all a continual becoming.
