I find myself here needing some help on how to talk to one of my best friends. Though she has not been officially diagnosed with BPD, it seems to be the only thing that 100% explains her behavior.
Her and her sister are two of my best friends, so just in case I will be calling them "Diane- BPD" and Michelle "the worried sister".
The main issue that Michelle and I are noticing with Diane is that she has MAJOR jealousy. Jealousy to the point of pulling out her hair and placing it on the pillow of her "boyfriends" bed so that "all the ****** will know" that he is taken. Oh, totally didn't mention this... she is also married! And is extremely jealous in her marriage as well.
Michelle and I are wanting to talk to Diane about her issues, but she is in complete denial. She has no clue that what she is doing is not only wrong, but comes off crazy and unstable. We are scared that this could lead to much more violent behavior, especially if she loses one of the men in her life. So how do we go about talking to her? I know that she will be offended, be defensive and even down right angry at the two of us, which is okay to an extent. But how exactly do you talk to someone about their mental state when they don't even think that they have a problem?
