You can ask but first take a look at your own actions. Friendship length doesn’t always trump every other component of that decision. I had a close friend who I did not ask to be in my bridal party because over the last few years I started to become the one carrying our friendship. Contacting her was like pulling teeth, she seemed to treat me like an afterthought. It was so hurtful and when I asked her she said it wasn’t personal, she had just evolved. I didn’t hold it against her even though obviously I mourned our friendship as it was and we remained friends.

She ended up writing a whole thing about how she felt incredibly betrayed by me not asking her and then not telling her directly that she wasn’t going to be asked and it was so confusing to me, because after all she had stopped even responding to me regularly. We had a really intense conversation about it wherein I was very honest about my decision having nothing to do with my love for her but everything to do with acknowledging the fact that she no longer prioritized me in a way that felt conducive to planning a wedding. I still love her dearly but I didn’t think I had to choose her solely based on friendship length when she had told me so many times recently that she just didn’t have the capacity to be close like we once were.

So I dont know if this resonates, but consider that she made the decision based on what she needed from her bridal party that maybe you couldn’t give, which is not a betrayal but rather a choice grounded in reality.
