"CAN I ASK: What do you mean "act as if, but not tell him" act as if I am dating?"
So much of this (DB'ing) is just a kinda mind game. 99% of the time you could effect a change in your R and never say a word. As an example. Just walk down the road and wave at random people.. most of them are going to wave back. Or just standing somewhere in a group of people look down and point at the ground.. chances are most of the group will look down with you. People respond to actions and what they see. Imagine if you were in that same group and just said "Look down!" what are those people going to be looking at? I got money they won't be looking down.. but right at you trying to figure out why you just said that. I understand that you can't "see" him. But if you talk to him on the phone.. smile.. even if you are mad. If he texts/emails you crap.. don't respond. Simple things like that help.
