In fact, OW may know, or hear about how your H is regretful sometimes and missing you. She may have done this hair thing just to make you angry so she can say to your husband, "See what a bad temper she has!!! Why on earth are you missing this woman?"
Hmmm... good point ROOT. I do know that ow is VERY insecure about her place w/stbxh and is trying to push everything along more quickly - H moving in, integrating families, etc... Not to sound paranoid or anything but I honestly believe that she does a lot of this stuff to "one up" me.
