This is an awesome update. Enjoy this time together - this is so much farther than many of us have gone. I often recommend to others here that they go back and re-read their situations to see just how far they have come, and to remember how bad of a space we were all in before.
There will be time for R talks - but I think if you jump to those too quickly, it will scare him right back into that tunnel. There are some good posts in the MLC forum and Words of Wisdom from the vets threads that discuss some of what happens in Recon - I might recommend you read them.
One thing I know for sure - take it slow. I would even say that to him if he broaches the subject of R - I want to take this slow and see how things go.
In the meantime, I don't think there is anything wrong with enjoying where you are right now. It's sort of like getting to know each other again.
Glad to hear of your news - stay strong and take care
