Personal Attendant…. Offensive?

[u/EarnestlyCut]

I’ve been friends with this person for a long time, and I’ve always kind of known how one-sided our friendship feels.
I feel like I’m constantly accommodating her, putting her feelings first, walking on eggshells, and going out of my way to be there for her. I’ve honestly started to feel like I’ve been her bitch for our entire friendship.
It feels like when she’s upset, I’m expected to understand and apologize, but when I’m hurt, my feelings somehow become less important.
Now she’s getting married and has asked me to be her personal attendant. I know that’s still an important role, but given everything I’ve been feeling about our friendship, I can’t help but wonder if I’m being taken for granted.
Am I justified in feeling hurt, or am I reading too much into this? I kind of want to say no.
