I don't want my daughter's dad to walk her down the aisle.?

Ok, well, this sucks. The way I see it, totally an opinion, it's either find a way to just clench your teeth and deal with it, because TECHNICALLY it's not your wedding, or maybe you should talk to her. If she's a good daughter, she might understand. But you got to realize, it's an extremely important day for her, and if I were her, I'd want my dad, idiotic jerk or not, with me.
