My mother

Is not coming to my wedding, because I invited both my grandmothers. Both are hers, and they hate each other. My Nana Joy adopted my mother from Nana Jeanette and is not coming to my wedding cause I refused to uninvite my grandmother. I have spent the last week on bed rest, and needless to say this has stressed me out. I mean she is my mother? Is it too much to ask after the allowances I make for her, not calling, not texting, not f-cking pigeoning me for her to come to my wedding?
I chose a wedding dress I hate because she loved it (she hated my favorite) cause I knew I didn't she wouldn't come to my wedding, now she isn't coming anyway, what does she expect from me? All I have ever wanted from her is for to act like I am her daughter not her best friend.  My mother has never been there when I've been in hospital or even texted back. When I was raped by an ex-boyfriend she told me I'd deserved it.
I don't know why I keep trying but I can't understand why she won't come to my wedding, I am her daughter when all is said and done. And isn't a wedding what all parents want for there little girls?
