Hello everyone, I wondered whether I might be able to get some advice/an outside perspective on a situation that I'm really stuck on.
I'm only just engaged (1 month ago) and so haven't really done any planning for my wedding and probably won't get married until 2016, however I do have an idea of who I want to be my bridesmaids.
I was speaking to my mum last night and she found out that I wasn't planning to have my sister as a bridesmaid (my sister is a disabled adult living in sheltered accommodation, she's mentally disabled, but it's not too severe, she's also about 4ft10 and around 15 stone) and she got very angry and upset with me.
My mum said that brides always have their sisters as bridesmaids (is that true?) and that especially as she's disabled and won't ever get married herself she should be in my wedding.
I'm not that close to my sister, and so I'd prefer to have friends that I'm closer to as my bridesmaids and who can actually help me with wedding things rather than having to be looked after. Also for very shallow and selfish reasons I don't want her to be a bridesmaid as she's so overweight.
My fiancé doesn't have any siblings to include and my brother isn't going to be a groomsman (although I am going to ask him to walk me down the aisle as my dad passed away a few months ago). I was planning on giving my sister a special job, possibly reading a passage about love (Corinthians) that we had at my Dad's funeral, which I thought was a lovely tie in as my dad won't be there and maybe announcing us as Bride and Groom, so that she feels involved and more special than being a bridesmaid.
My mum told me she was planning on putting some money into the wedding, but that she'll only do that now if I have my sister as a bridesmaid (on the condition that she loses a lot of weight - which is very unlikely anyway). I could agree to this, as it's unlikely my sister will lose weight. But I am unhappy that my mum is basically trying to blackmail me into this and that she's already making demands.
She also hinted to my sister that I might have her and now my sister keeps asking me who my maid of honour is going to be.
I don't know what to do, and I'm feeling rather stressed and upset about the situation. What does anyone think of the situation?
