I loved this article!  Ghost Dad Phenomenon is a perfect way to word it. 
I was told I was going to died and travelled to the US to have a stem cell transplant for Systemic Scleroderma. My husband walked out when I told him I wanted the kids to come with me. He then proceeded to take me to Family Court during my chemotherapy. He Skyped the kids daily and  resented him for it. He took my insurance money for my illness he then tried to take my home, which I had paid the mortgage out. Later I found out the little design company I own was totally his -  he did the set up - for himself! As I got sicker I had tax loses in this company which he now uses to get his current income down for Child Support. He has nothing to do with the children and has never bought them a Birthday or Christmas gift. He wont pay for medical and my son has needed 2 operations which are left to me to pay. I can't work due to my illness and life is very poor. The ariticle is so true!
