So long story short, my mom has dementia and will not be at my wedding. My dad has a girlfriend who I'm assuming he's planning to bring - and I wouldn't exclude her because even though the entire situation is sad and bizarre she's actually very kind and has been very caring towards my mom. I don't know what to do - I am planning to include my mom's name in the invitations with my dad but I don't know if that makes sense. I know people may assume that my dad's girlfriend is my mom so I'm not sure how to address that (if at all). I want to figure out some way to acknowledge my mom without making it seem like she's dead. I just feel so mixed up about the whole thing, help!
