I have visitation rights and my ex girlfriend has sole custody. I see my son 3 weekends out of the month, the first Wednesday of every month, his mother and I alternate holidays, split winter break, easter break, etc,. My son is 12 years old and will be 13 in January. He has lived with his mother his whole life. A little while ago, he told me he wants to live with me. I told him to talk it over with his mother. His mother told him no, and also talked down on me to him. I have been in my son's life since day one. I always pick him up, never miss a child support payment, i go to parent/teacher conferences, attend his sporting events. I do everything i can to be a GREAT father. We both live in NJ but his mother live 20 minutes away from me. What steps do i take?
