It's ok to have R talks in piecing -- in fact, you'll be having lots of them.
"Honey, I want to ask you something, and please be honest with me. We've been through a lot, and I'm really happy -- but honestly, a little scared, too -- about how things have been going lately. I want to keep making progress, but I don't want to smother you, either, but I don't want to pull away so much that you think I'm being cold, or distant? What works best for you? How can I help you?"
Coach used to say that "How can I help you?" was one of his most powerful things to say to Greek, and she would say that she loved it as well. Very validating, and OFFERING to help fix, but not trying to FIX RIGHT AWAY.
