I have missed T on occasion if one or the other of us has been gone. I missed 3 weeks this past summer when I was on vacation, and the occasional odd week when I have been out of town or he has been gone.

I have told him that I missed him and it wasn't really a big moment or anything, it just seemed kind of normal. It was acknowledged and we moved on, very much like I might tell someone else in my life that I missed them if I didn't see them for a bit. Not a terribly big deal.
