Have a friend, met through our dc but they are adults now. She isn't someone I'd usually choose as a friend. We have very different values but I also like her, she can be fun and kind. However she can also be quite mean and cause a lot of drama.
Over the years she has upset me many times. She always over steps the mark, talks to me like I'm an idiot or a child (she is 10 years older) I'm sick of her unsolicited advice. She over steps the mark, makes really rude comments about my relationship because she doesn't like my partner, says inappropriate things to my teenage daughters like 'find a nice man with money' 
and I'm tired calling her out on these things and then dealing with the drama that ensues. She always says things like I'm sorry if I upset you but she never admits she has over stepped the mark, just always claims she wants the best for me.
Aibu to think we will never overcome these difficulties, this is who she is and we are just not compatible friends (unless I suck up the drama and upset) I'm tired of the fallouts. This happens with almost all her friends, she falls out with a lot of people.
