Hello, my maid of honour is my younger sibling who I grew up very close to. They happily accepted being my maid of honour and were initially very excited. Our relationship has fallen apart in the last few years on the back of our parents divorcing and now, 3 weeks until the wedding they won't speak to me, return my messages, anything. I just don't know what to do, after failed attempts to meet up I sent a message 2 months ago outlining the very minimal requirements I need for them to be my maid of honour but still haven't heard back. Those requirements are that they speak to me and show love and support to me. The cited explanations are mainly mental health prevents them being able to work with me and also a rather long list of all the things I've done wrong in my life that makes it hard for them to have a relationship with me and hard for them to love me. Things I've done wrong mainly consist of making them feel inadequate or judged by teasing or talking to much about myself.
I've had to get my other bridesmaids to do all the work without help including the bachelorette party etc. I have not seen what the maid of honour is planning to wear, I know there is an outfit because they've shown our mother. I feel it is completely wrong and unfair to let them continue and allow them to remain in the bridal party unless things improve but I've just run out of time and don't know what else I can do.
My sibling doesn't speak to our father and very rarely to every other family member we have except for our mum. Mum is extremely distressed but continues to get involved which I believe is not helping. Mum is the only person with an active relationship with both of us and I tend to be rather resentful of that, other family is also hurt by the neglect. Mum keeps getting upset with me because I'm preparing to remove my sibling from the bridal party if they don't respond to me this week, I've been in trouble for talking about the issue with my other confidants, I've been challenged on how necessary it is for me to make a fuss about it, it's been suggested I be more sympathetic about my sibling's mental health but I just don't feel I can bring myself to roll over on the issue.
The goal is to have the most positive day possible without loosing my integrity. Suggestions?
