How do i tell my father that my step father will be walking me down the aisle?

Just politely tell him that stepdad is walking down the aisle. Your dad should be able to figure out why.

This. It sounds like your father shouldn't expect to walk you. Much like my father, he hasn't earned the privilege. It's so great that you have another wonderful father figure in your life and it'll mean so much to him to walk you down the aisle.

Exactly this. You don't need to rehash the rough past with your dad. You just need to tell him that your step dad will be walking you down the aisle. End of story.

My mom walked me down the aisle because my father and I don't have a great relationship. I honestly never had a talk with him beforehand to tell him he wasn't walking me down the aisle. He figured it out on his own (probably because we didn't talk about the wedding at all and he wasn't invited to the rehearsal dinner).

I personally feel like bringing up things people aren't going to be doing or be involved in (ex: telling people they aren't in the bridal party, telling people they aren't invited) is awkward and gives people the opportunity to argue why they should be included.

If your father hasn't/doesn't asked you, I wouldn't say anything. When he does just tell him your stepdad is walking you. The first time I got married I didn't chose my dad or step dad. This is my second marriage so the idea of anyone walking me down doesn't sit right with me anyway. FH and I are walking together.

I feel for you. Strained relationships with family is difficult. It's your day and you should do what you want. You don't need to ask in a subtle way. This day is about you and the people that have supported you over the years. People who have never dealt with this will never get it. I recently started healing my relationship with my father that was once strained. He is making huge improvements and efforts so I have decided to have my mother, step father of 13 years and very supportive, and also my father walk me down the aisle and I don't care if anyone has an issue with it. Good luck with everything!

Oh no! Your step-dad should know that it's hard for you to have a bio dad and a step dad you consider your dad. You were just trying to be nice and considerate of your inconsiderate father. Hopefully it will blow over and all will be okay. It's hard when parents don't act like adults. Perhaps you can explain to step-dad your thought process and he will understand!
