for the most part, i think you came across as weak... the "memories" comment... commenting on whether or not she had planned a night out... the "you don't have to give me the details" remark... "i'm sorry you feel you need to do this," no bueno!!! you are too attached... the less you say, the better--especially if you are going to make these types of comments...
Before leaving, W seemed to think that I had been controlling and insecure. I hadn't been at all, I had just wanted us to make some time together because we'd only had 1 night out in 6 months. Of course she could just have been using poor excuses but for me to say after we split that I'd take the kids if she has a night out planned and I didn't need to know the details, it was a total 180. I was self-confident enough to let go and not be bothered what she does, so I think I seemed less needy to her. I effectively took a step-back. Strangely enough she then told me the details of what was planned even-though I had said it was none of my business.
