A lot of times we get so caught up in the DB mantra that we forget common sense. Do what feels right. Every interaction can be a positive interaction if you make it so. How would you act if he was a close friend? I doubt you would be all over a really close friend. Do not be distant but do not be all over him. Guys like space and a chance to breathe but they also like attention.
Remember, IMO, all the DB advice is a good blue print but in the end you have to adjust to your specific scenario. As you know I went to OK in April, that was shortly after my D was final everything in the DB universe was against it. I went. I think I had a GREAT visit and a lot of positives came out of it. If I had not gone I would have wondered.
Test/Evaluate/Continue or Adjust
This is a great chance for you guys to hang out and have some fun (beginners mind). In top of that your H recently did a C session and that is very positive so pretend you are seeing a very close friend and enjoy yourself.
