xW continues to try to stop by my place in the mornings that I have custody of our S's, to give them hugs before going to work. It just seems so pathetic for her to insist on forcing herself into our kids time with me, like she cannot bear for more than a day or so for her influence to not be exerted upon them. She's become so darn anal and insecure.
I would put an end to this if you can. It is disruptive and interfering with your time/bond with the kids. I would simply tell her that she is no longer welcome in/around your home on these mornings. If she must see them she can do it at the school or something.
