Her reply about just staying in a loveless marriage and not divorcing, I feel, means SOMETHING. She is clearly fighting with her decisions and is still extrememly confused. She knows she is not happy, wants things to change, but doesn't know what she really wants. You need to work diligently on your 180's, Steve. Really really focus on her complaints. She obviously doesn't want conflict. Nobody does. Instead of responding to her with tit for tat, or even by listening, just avoid the conflict as much as possible. Avoid ANY conversation that may cause emotions to stir. If she initiates it, you just respond as a listener, a validator......Stay your course. I really feel she will settle down a little and look at things more clearly. Remember, happy interactions, upbeat, fun, light and fluffy.
Very happy to hear you had some good quality time with Daughter.
