A bit of background so people understand and don't just start "you can't" right away.-- I was previously engaged and had chosen my bridal party to be my sister(moh), his sister, and a childhood friend. My ex ended up breaking off that engagement about 5 months before the wedding, but no one had bought dresses or anything, so there was no money commitment of any sort.
I am now engaged again(to a different guy) and have started picking my bridal party. The childhood friend apparently said something to my mother a few days ago about being my bridesmaid still and my mom said it seems like she thinks that she is still being included even if I haven't asked her. I've grown pretty apart from her in the nearly 4 years since I asked her to be a bridesmaid for my previous engagement and really have no desire to have her as my bridesmaid for this wedding. I'd really like my bridal party to be only family- my sister, and his 2 sisters.
What I'm wondering is what a nice way to say "sorry, but it's not a lifelong invitation"? The only time I see this girl is when I am at my parents house in another state and then usually its only for her to drop her son off at their house for me to babysit him while she and her husband go out to the bar. My wedding is over a year away, and who knows how much more we will grow apart by then.
I've seen a few other places where people say that there are no "take-backs" on bridal party invitations, but there has to be some way around that for a casual "oh yeah, you can be in my wedding" when its been over 4 years. Any help please?
