Krittyk, I don't think you can say it enough. I have a philosophy, that I tell my wife I love her everytime I talk to her whether on the phone, in person, or before either of us may be leaving to do something. I want her to know how much she means to me.
If something may happen to either of us, we know that we had said it to them, and we would never have to say, "i wish I had..."
romantic? Yes, I am, and proud about it.
