And how does reminding yourself of this help you? I realize that the physical contact is out, but short of that does it help you to keep you expectations to zero? It doesn't sound like it. It kind of sounds like it a big ugly stick you use to beat yourself up with. If that's the case....you might want to burn that stick.
Enjoy the roses as a sing of caring if nothing else. That's sooo not a bad thing. Really.
