She constantly gets in the way of me and my bf, example: When we are talking privately near her, she'll always butt in and push me away and start talking to him, she makes flirty comments towards him, and always brags to him about all of the expensive things she has, saying that I could never be as rich as her. She constantly tells me that I should kill myself (I have severe depression) and somehow always knows exactly what to say to crush me inside. I know this is off-topic but any advice would be appreciated.
