Help with my Taurus mother!?

My mother and I have never gotten along. I am a Leo, she is a Taurus. My entire childhood she used her gifts as an excuse to not have to spend any time with my sisters and me (ie. "I bought you ____, _______ and ________. How dare you say anything I do is wrong?). She is also a firm believer in psychiatric pharmaceuticals, and the fact that all her children need them, whether they truly do or not. I am an adult woman who has been out of the house for almost two years now. I am attending college and doing fairly well in my cles. But all I ever hear is how I need to be back on meds, despite doing well in life. I am living with my soul-mate, and we plan on being married soon. However, because of my future husband's lack of material recourse and monetary funds, she refuses to come. As a Leo woman, this hurts me but it also hurts my cancerian fianc�, who truly can't understand why she hates him. Lately she has been leaving nasty messages on my email and facebook, and is encouraging other family members to do the same. I am growing tired of this, but feel some moral obligation to not block my mother completely from my life. My fianc� also hates the thought of me disowning my mother, but is tired of her abuse as well. From an astrological (and common sense) standpoint, should I kick my crazy mother out of my life, or just deal with her to make my conscience feel at ease?
