<human>: Hello everyone!
Up until recently, my bf's mother and I used to get along rather nicely. We would exchange Christmas gifts, I would spend time in her house and help with cleaning and cooking, regular stuff. 
All seemed well, until a couple of months ago, when she started to say some unpleasant things like comparing me to my bf's ex and how I'm to tall, that my bf spent to much time with me, etc. So did my bf's brother, but not wanting to stir up any drama, I just ignored it. Recently, she got mad with her son, and acused me of influence him, even though I had nothing to with it. I was really hurt, because I always tried my best to help his family and to support them during tough times. That being said, I was willing to forget her mad phone call and put it behind my back. But she was not, and one day when I had to leave in a rush she made a huge scandal saying I was rude, I was a bitch and so forth, even though I was cordial to her up to that point. His brother has also fueled the argument. From that point, the texts, Facebook messages and thrash talking started. I decided to ignore them but that made the rage worse. On my graduation  she got all abset that I didn't say hi to her (I was afraid that she would attack me and cause a scene) , and started crying and sender me a long text of how she expected that my career was a failure. She now constantly fights my bf to the point where she slapped him. He has been great, and defended me even after I suggested that he should just tell her that we broke up. He now says he's gonna leave her house, and even though there are some other motives behind it, I can't help but feel responsible.  I don't wish to destroy his relationship with his mother, but I don't want to loose the best guy I've ever met to some crazy lady nor cause him problems. :( on the other hand, I see the future of our relationship is somewhat compromised because of his mother. All of the other family members seemed to like me and are very nice.

Can you give me a shortened version of the text?
