"Afterwards, as I didn't say very much during the call at all, I thought I might have been too cold so I called her back and asked her how her garage sale went (it was this morning)."
You have to stop the calls immediately. If you don't, how is she ever going to "miss" you. You have nothing to apologize for. If she feels that you were "cold", so what?! Deal with your hurt your own way. She's doing it to continue making herself feel better.
Look at your post again. She's not doing it for you. She's still doing it for herself. If she calls and you miss it, too bad. That's what happens when you're separated. You no longer have to answer to her.
If she calls angry saying that you didn't pick up the phone, tell her sorry but you were busy. It's the reality of the sitch that she's going to have to learn and the sooner the better.
Dim means to not engage all the time. Every time she calls, you're still jumping at the chance. Stop thinking about what she thinks about your behavior. You're going to end up second guessing yourself and end up being so confused that you're going to forget who you are.
