Perhaps you're right. Maybe it's a half-hearted attempt to prove to the X that I am not unwanted.
Sweetie, if this is in any way about proving anything to anyone, including X, then you aren't ready. Period. I recently started dating, and I'm having a good time. But that was a year after Mr. P moved out, and a 18 months after BD. During that time period, I figured out how to be at peace with myself and what I want going forward. I did a lot of GAL, but with other women or in a group. Give that a try first, go out there, try new activities, pick up a hobby, learn something you always wanted to do, but don't date yet.
