issues with my mother

So just to give a bit of a background. I am 28, so this is no where near a teenage rant session. My entire life my mother has been abusive. She has schizophrenia, but I think it's more borderline personality disorder. She used to steal things from me and my sister and pawn them off to get money. We lived with my grandparents and she used to steal from them too. They did nothing to stop the abuse.  They felt sorry for her too much to kick her out. She used to beat me down emotionally all the time. I remember I never felt comfortable around her because she would always start fights with me. As we got older I was the bad child and my sister was the good one. It started to put a wedge in our relationship as well as my sister never felt the abuse I did. 
Anyway fast forward to my current issues. I am planning my wedding, and as a common curtesy I called my mother to ask her if we had it on a Friday would she be able to make it. She said yes and started asking me things I was planning for the wedding. The first argument started when she said "so have you asked your sister to be your maid of honor yet". I told her I wasn't going to because I wanted my best friend to be my moh. Me and my sister are not close. She preceded to get very angry about it. I managed to change the subject to colors I was thinking. They she said "so should I ask your uncle to walk give you away or do you want to?" I was thinking of here we go. I told her I didn't t want him to because again, I'm not really close to much of my family. I feel like all hell broke lose at the moment.  She started yelling about "oh so you're going to have a non family member give you away? You're so ungrateful look at all we've done for you." And then she started naming off things normal mothers don't expect praise for, they do it because they are mothers. Ugh at this point she was just screaming at me so I hung up on her. She called me back repeatedly but I didn't pick up. I ended up just blocking her number through my iPhone. I don't know what to do because my fiancé parents really want to meet my mom, but I don't even want her at the wedding. The problem is she is living with my aunt now so if I don't allow her to come, half the family will not be there. Including my grandmother who also lives with them now. I really need some advice guys....
