Hey!!! I think it was a posistive reaction. I honestly think it was a positive reaction and I dont really like your wife as you know. Granted how she behaves, I was totally surprised she even mentioned the letter... I was prepared for...silence.
I bet the I love you made a huge impact, I can feel it. I agree,dont let her beat around the bush much. I dont think you should wait another 2 months to at least have another duiscussion. Since she said you misunderstood her about the C tell your C about it and see if you can go even if she feels she doesnt want to respond yet.
I am with Amy, how does it feel to show you are not "settled"? At least that you dont intend to stay settled for much longer? Love ya K
