Do not do any 'us' or R talk. Bite your tongue! If you have to step away, do it.
The first time my W did anything after our talk, it was all I could do to hold it back. I didn't bring any of it up and we had a good day just talking like friends.
By not bringing that stuff up, she will be more comfortable around you because she won't feel any pressure.
It is a rollercoaster. As happy as you may feel after the outing, it will probably get worse as you will have expectations. Expectations = bad.
The mental images go away. Trust me.
