Learn to get along with her. In this life, you will come across lots of people whom you don't particularly like, but will need to get along with for the sake of peace in your life. Co-workers, neighbors, even people who marry into your family (or you marry into theirs). It's best if you learn to go with the flow and keep the peace if at all possible. If not, then by all means still go to visit your dad, but find someplace else to stay while you visit.
