I've no idea why she asked it but I just said, that I've been out with a few friends just having a good time with them.
Typically, the WAW needs to know that you are still around as a fallback in case her experimental new life situations don't work out for her. If you get too comfortable on your own, she may get nervous.
Your answer was perfect. Keep some mystery there, after all, it's you enjoying your life and she has chosen to remove herself from that for now. Your objective is to make yourself understand (very hard, and will take work on yourself) that you will be able to survive without W. When you have convinced yourself, she will also detect that, and may sense some loss.
