NAH - I would look into parental alienation. In some cases, one parent is willfully manipulating the child to reject the other parent, but oftentimes it is entirely by accident. You should NOT be in the middle of this. Your parents should be presenting a united front.
In this case, your dad should probably be keeping you out of the adult matter and shielding you from his pain as much as possible and encouraging you to have a relationship with your mom. I know that is VERY HARD for him to do, given what has happened, but it is part of being a parent. I highly recommend the book Overcoming the CoParent trap for both of them: https://www.amazon.com/gp/product/0692407995
It is a very quick, but powerful read.
