I know what you mean about feeling like you are dating again. That is how I feel most days. But, I love that feeling. It's like everything is new. No baggage, no drama. Just fun and feeling happy. It's all still there, but not as important.
I don't know if you remember reading it, but I feel like I built a fence. The crap from the A is on the other side of the fence and I will not allow it to come on my side. My side if fun, positive, friendly, and open to new beginnings.
