I know what you mean about not going overboard. I have been making sure I let him know that I notice the little things he does. I either tell him in person, in an e-mail or in his lunch box notes. I try to keep it simple, but still worry that is too much sometimes. He tells me often that he likes my notes, so at least I am sure that isn't going overboard.
It is so good to know that someone else has gone through this and has overcome it. You've been here a long time. I've read some of your posts, but I can't remember if I found your thread and read some of it or not. I've read parts of so many. Are there things you and your h are still working on?
