Fear of abandonment. People with BPD are often terrified of being abandoned or left alone. Even something as innocuous as a loved one getting home late from work or going away for the weekend can trigger intense fear. This leads to frantic efforts to keep the other person close. You may beg, cling, start fights, jealously track your loved one’s movements, or even physically block the other person from leaving. Unfortunately, this behavior tends to have the opposite effect—driving others away.
