They have known each other since middle school. She claimed she was sterile due to a childhood accident, they had sex, she got pregnant, although he would like to have a relationship with his son she makes it so painful and frustrating that he has told her just to stop, he doesn't want anything to do with her. I tried to help her as she bounces from friends apartment to friends apartment with her son, my grandson, I got her a computer so she could pursue online courses, bought her tires, gave her furniture, told her I would help her in any way I can, I am paying the child support my son can't afford. She has decided I can no longer see my grandson and is harassing me about my son and the child support. We need help.
