Regret not having dad walk you down the aisle?

My family has always been extremely close except a couple months before I got engaged my parents filed for divorce (after 30+ years). It’s not amicable, they’ve been fighting over everything for over a year now. The court date isn’t until 2 months after my wedding.

It has really strained my relationship with my dad, to the point I’m not sure I want him to walk me down the aisle. I’m worried if we are able to mend our relationship after the divorce is final that I will regret no having him walk me down the aisle. He’s done some pretty ugly things to my mom and used me/the wedding to hurt her. We really haven’t talked much over the last year, went from at least once a week phone calls to maybe a text every 3 months. Him walking me down the aisle won’t mean near what it would have before all this happened and I’m worried it will feel fake since our relationship near non-existent at this point. I’m also worried I will deeply regret it if he doesn’t.

Both of my parents have threatened not to come. I’ve never had family drama before, we’ve always all been close so I’m having a really hard time dealing with this. I still talk to my mom but all she wants to talk about is the divorce, I’ve asked to be left out of it multiple times but that’s all she can talk about to me. It’s hard to get excited about your upcoming wedding when all you hear about is divorce 24/7 and 2 of your most important guests keep talking about not coming. Really needed to vent about crazy families just a few months before our wedding.
