I'm so upset, my dad wants to walk me down the aisle and leave. My Mom & Dad got divorced about 7 years ago and he thinks my mother will start an argument with him at the wedding. I've talked to my mom about this and she has conviced me that it is absolutely my day and there is no way she will do this. I've explained to him that there will be 100+ people at the wedding and they don't have to come anywhere near each other or talk to each other. I've tried talking to his sister to hear her opinion and she agrees with me that he should stay and that he will regret leaving in the future. She has tried talking to him too. My dad and I have been very close but in the last 6 months we have been arguing over other stuff which doesn't help. I cannot tell you how sad I am about all of this. Any ideas on how I can convince him to stay? When I think about how he won't be there to do the father-daughter dance, give a toast, or to see what other little suprises I have in store, it brings me to tears.
