My opinion, is that you did want you thought was right. In a way you are controlling your wife actions, but her actions are not considering the group or your D. She is focused on her own wishes. It could be looked at that you backed down by coming to the party but you stood for the fact that you did not want the OM there and you would take the reprecussions accordingly. YOu also had a plan for your D for the weekend you had her to celebrate her birthday.
The issue, as it is in my situation, is that your W is used to getting what she wanted regardless of how it effects people. So her having to think about others right now is something new to her and she does not know how to react. I am going through this right now with th ecustody of our son. She does not know how to react when I take him to do things that I want to do without her approval. It is a learning process for them. Focus on you and your D and you will be in the clear...
