I am so happy for you....a very happy Anniversary afterall.....you handled it beautifully.
I hope you don't have one...but don't be surprised to see him pull back a little bit or even say stuff like it was a mistake. It doesn't sound like it from your sitch, but it is always a possibility.
It is normal to be a bit guarded. The first time my W and I ML after sep, I was actually shaking...it almost felt like our first time...very awkward.
Congrats on a great evening, I would let him take the lead on a new get together. When you see him for the paperwork, just say something like "I had a a very nice time the other night" so he knows that you don't think it was a mistake.
