W called as I was driving in to work. This time I answered. She just asked how I was doing, how the dog was doing. Mentioned that she had called a few times and couldn't get hold of me. I gave one word answers to everything and didn't engage in anything.
I know it came off a little cold, because she ended with "Well, ok then..." in a tone that showed a little frustration.
No no no no. Come across as happy and upbeat as if you have already moved on and your life is perfect. Being cold is not going to win your wife's heart back. I know it can be confusing how to communicate when you are being LRT. In text messages you can be short. When she calls, be happy and positive, as if you would when face to face. Do not go into details, but when she says she called and could not get ahold of you, say something like "Yea, I saw where I missed your calls. I have been so busy with work and friends it slipped my mind to call you back." Or something like that. It makes you mysterious and makes her realize you are not obsessing over her.
Zew, this ^^^^^. It's the whole "the best revenge is a life well-lived" thing.
C'mon, you're better than that. Do NOT come across to her as pining or pissy. You are THE MOST INTERESTING MAN IN THE WORLD, scaling mountains, saving babies from burning buildings and meeting other incredibly attractive, interesting people, remember???
