Why does my ex wife want me to sit next to her while we watch my girl in a school play!?

There is no love like a happy family and thats what women do is make a family happy. When a marriage fails and the family is broken its the worst feeling to a NORMAL woman because that means she failed. To sit next to you, to me, that would seem like she want to remember what it felt like to be family. Espically if the divorce was her fault. Enjoying watching your children together should be a soothing and enjoyable an she misses it.
