TM, She is in panic mode because she now senses that you are standing your ground and distancing yourself from her. Why would you go to court and get the filing overturned? She's the one that filed and she's the only one that can stop it. Again she's looking for someone to take care of her.
Your stbxw has a very funny way of showing you that she wants to work on the relationship. Kisses don't make the boo boos go away...hard work does. The leopards spots are coming through loud and clear and unfortunately, she's got a lot of work to do to become a mature woman. She is still playing as the little girl who needs rescuing.
I'm glad to see you went out and had some fun. It's about time that you did something "fun" for yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
