My Dad walked me down the aisle. I actually didn't want him too, he had an ABI and was pretty unbearable to be around, I did it to keep the peace. I wanted someone else who was more signifant in my life. I still had a memorable and beautiful day as it was all about the man waiting at end of the aisle for me.
If you have or had a good relationship with your Father, then that's great you can share your special day with him.
If not, choose someone who has impacted on your life in an important way and always will, man or woman or stand tall and go it alone. Just my opinion.
