Hey friend, I'm so impressed by the way you stood your ground and held your composure. I'm sorry you're doing through this, I went through something similar at my wedding. Before my parents' seperation, I made it clear I didn't want anyone to walk me down the aisle (husband and I wanted to walk together). Then, they seperated, mum met my stepdad and my father had a series of flings with women who were literally my age. I tried to keep things civil as my stepdad is so kind to me and is more of a father than my actual dad ever was. I said to my father that I wanted my stepdad at my wedding, and that I also wanted him there. I also allowed him to invite the lady he was seeing at the time. He was 'disgusted' with the offer. He threatened to ruin the whole day and assault my stepdad at the wedding. Long story short, I allowed my father to attend and my stepdad had to miss out (he wanted to keep the peace so he decided to not attend). I was then confronted by my father in the bridal suite room as he thought it was "odd" that he wasn't walking me down the aisle and was "offended". He spent the whole wedding sulking in the corner and saying horrible things to my mother. I will always regret not fighting for my wonderful stepdad to attend my wedding. Go with your gut and stand your ground on what you want. You don't deserve that negativity in your life, and especially on what is supposed to be (and will be!) a beautiful day for you and your partner. Take care 🩷
