In their minds, their needs and wants surpass the needs and wants of others.
They often abuse, control, and manipulate their loved ones, playing on guilt and a sense of obligation to control the people around them.
Also, you need to know that the dysfunction BPD creates in a person's life cripples their emotional capability and understanding, so it's likely that you will not be able to have an emotionally mature relationship.
People with BPD are not accustomed to receiving compliments.
You will also be able to reinforce better, productive behaviors. They yell, threaten suicide (and are sometimes serious), accuse, blame, and are highly defensive.Realizing that your loved one has a completely different emotional perspective will help you protect yourself and stick to boundaries.With BPD, knowledge is power, and if the person doesn't know that he has the disorder, and the people around him don't know it, they don't know why their loved one is acting that way.It would be like faulting a person for getting cancer.However, this is not a reason to allow the person you love with BPD to manipulate or abuse you.
