So here's the deal, we're putting together our guest list and my father has come out strongly against me inviting his sister (my aunt) due to bad blood that has developed over the years stemming from the passing of their father. To my father, she is dead to him. However, my aunt and I have a good relationship and I want her at my wedding. However, I do have concerns that they may not remain civil throughout the day. My fiancé and I are paying for almost all of the wedding ourselves, my parents did help out with about 20% of our current budget. I just want to have my whole family there while I get married. How can I do this and keep the peace?
