Interesting mix of feelings

Tonight my mother came over and insulted my husband and called him "ruthless", then she insulted my mother in law calling her "inept" and I told her I did not want to have this conversation with her and she should leave. As she was leaving she told me I was "in denial". It was just weird to begin with, but then about 15 minutes later she sends me a text message on my cell phone that said "Judas kissed Jesus". So now I'm a traitor too? I'm angry about what she has said about myself and my family, but I'm also amused that she is being so childish. I am also a little hurt that my own mother, who is supposed to love me can be so awful to me. She doesn't show me love. She shows contempt for me and for my family. I understand that she does not like my mother in law, and honestly, my mother inlaw does not like her either, but I did NOTHING to instigate a fight with her. And how dare she just walk into my house without knocking and insult my husband! I was standing in the kitchen doing dishes! That's it, nothing more. My mind just cannot wrap around this tonight, and I feel the need to vent, but I don't even know where to go from here. Mark says she's jealous that I am fulfilled in my life. I've got a wonderful husband who loves me dearly, and my children are absolutely wonderful blessings, and I love them and they love me. That's more than she's got. Her kids don't even live with her. They lived with US for the last 2 years before moving in with my husband's employer. Ugh, a whole other nightmare story. Not to mention that she did all of her insulting tonight IN FRONT OF MY CHILDREN!!! I have now instructed my children that when they come home from school, they are NOT to stop by her house, but to come directly home, and we are to keep the doors locked at all times and NOT answer the door to her. In the meantime, I've got a lot of thinking to do, but at this point I need to no longer have a relationship with her. I cannot continue this rollercoaster ride that is my mother.
