I am so glad the conversation went so well, I hope he is willing to keep on the path he is with working on being comfortable talking about things. I've seen so many situations be worse than they have to when the hinge was assuming their partners wouldn't be OK with things/information so they keep quiet aren't upfront. It always seems to make the situation awkward for all parties.
Yay on having a lovely evening with him too! And that article by Pema is interesting and helpful by the way.
Happiness will never come to those who fail to appreciate what they already have.
