My dad has somehow split my mom into two people. She is his wife at times and other times a stranger that is taking care of him. He is always looking for my mom even when she is right next to him. He is having difficulties with who his kids are. He recemtly told my mom i was adopted which i was not. He thinks there is always people in the house besides us 3. How can we have testing done when he will not agree and thinks there is nothing wrong with himself.
