I have four girls with a woman who hates me with a passion. I was with this woman for 15 years. I've always been there for my kids and try to give them whatever they need. I only signed the birth certificates for three of them. When she's mad, she tells me I will never see my kids again. What rights do I have or what can I do? We have no communication. She talks to me through the kids, curses me out in front of my kids. Please help?
